Rear Side Door Actuator Control Module
The rear side door actuator control module is capable of on-board diagnostic functions described in On-Board Diagnostic Features . The rear side door actuator control module monitors the door position at all times including during manual operation. After activating the on-board diagnostic modes, loosing battery voltage, or ground to the rear side door actuator control module the Power Sliding Door (PSD) Re-Initialization procedure must be performed in order for the rear side door actuator control module to correctly determine the door position.
Power Sliding Door System Description
The power sliding door system(s) can operate correctly only if the power sliding door is in proper mechanical condition. Any mechanical problems will affect the power sliding door operation and must be repaired before attempting to diagnose the power sliding door system. Manually open and close the power sliding door to determine if the door moves smoothly and without excessive resistance or binding. The power sliding door must also latch and unlatch without the use of excessive force. At any time during power sliding door open or close operation, excessive resistance to the door movement will cause the power sliding door to stop and reverse the direction of travel.
The power sliding door will operate only when the power sliding door on/off switch in the overhead console is in the on position. At anytime during power sliding door operation the on/off switch may be turned to the off position and the system will quit any function in process. The power sliding door will not open unless the transmission shift lever is in the park position and the door is unlocked. When the sliding door security lock is in the locked position the power sliding door will not open from the inside. The power sliding door close function will operate when the vehicle is in gear. The power sliding door module uses the VSS signal to determine if the vehicle is moving during a power sliding door close function. The momentum of the vehicle moving forward adds resistance to the door closing operation. When the rear side door actuator control module determines the vehicle is moving forward while closing the door, current flow through the actuator motor is increased instead of being reversed. The VSS signal circuit is supplied battery positive voltage through a resistor then monitored within the rear side door actuator control module. The VSS signal circuit is then pulsed to ground, or pulled low by the powertrain control module in relation to vehicle speed. The sliding door alarm will sound repeated short tones whenever the power sliding door system is turned on and the door is open while the transmission is out of park.
When the power sliding door system is on and manual operation of the power sliding door is detected the rear side door actuator control module activates the power assist feature. When the power assist is activated the power sliding door will continue to open or close without any further manual effort.
The power sliding doors may be operated using the Remote Keyless Entry System. The keyless entry transmitter will have one OPEN/CLOSE button with a van symbol on it for each power sliding door. The power sliding door ON/OFF switches in the overhead console must be in the ON position in order to operate the power sliding doors using the keyless entry transmitter. When a right hand power sliding door OPEN/CLOSE function is activated using a keyless entry transmitter the exterior lights will flash once indicating the RKE module has received the OPEN/CLOSE command. When activating a left hand power sliding door OPEN/CLOSE function with the keyless entry transmitter the exterior lights will not flash.
On-Board Diagnostic Features
The left and right power sliding door systems operate as independent systems. The on-board diagnostic modes are entered and operate the same in both systems.
The power sliding door systems are capable of the following on-board diagnostic functions:
• Diagnostic Mode 1: An audible signal indicates the diagnostic trouble codes stored by the rear side door actuator control module.
• Diagnostic Mode 2: An audible signal indicates when inputs to the rear side door actuator control module are active.
• Diagnostic Mode 3: Performs an output test of the sliding door unlatch actuator.
Entering On-Board Diagnostics
The on-board diagnostic modes can only be entered in a sequential order from modes 1-3.
• Enter the right power sliding door system on-board diagnostics using the right B-pillar open/close switch and the right on/off switch in the overhead console.
• Enter the left power sliding door system on-board diagnostics using the left B-pillar open/close switch and the left on/off switch in the overhead console.
1. Both power sliding doors must be closed and in the latched position.
2. Place the ignition switch in the OFF position.
3. Place the on/off switch in the overhead console to the OFF position.
4. Press and hold the B-pillar power sliding door open/close switch.
5. While holding the open/close switch, operate the on/off switch through 10 ON and OFF cycles within 10 seconds stopping in the on position.
6. The sliding door alarm will sound 1 long tone indicating diagnostic mode 1 is active.
Diagnostic Mode 1
Upon activating diagnostic mode 1, DTCs will begin to be signaled by the sliding door alarm. The DTCs are 2 digit codes and the codes are represented by the number of buzzes for each digit of the code number. For example a DTC 12 is represented with the following sequence: buzz, pause, buzz, buzz, long pause. Each DTC will be signaled 3 times before proceeding to the next DTC. Refer to Diagnostic Trouble Code (DTC) List . The DTCs will continue to be repeated in this manner until the on-board diagnostics are exited or mode 2 is entered. When exiting the on-board diagnostics all stored DTCs will be erased from the rear side door actuator control module memory.
Yes, you probably have air in the system. Park uphill and run the engine with the heater on to get air out. Refill radiator. If air comes back or continues to bubble up in radiator, you may have a leaky head gasket.
no accumulator valve any where
the valve is a TX valve located at the evaporator coil and they can get a blockage
could be a thermostat problem
have an accredited ac specialist check it out and if damage related get a quote and present it to the insurance co
Does the belt turn the power steering pulley, I guess if it didn't it would make a racket.
With engine idling, cap off power steering reservoir, wheels turned one way or the other, can you see fluid swirl? If not maybe faulty power steering fluid lines or blocked.
I can't rule out the pump at the moment or the rack.
On some makes and models, I can take the belt off the power steering, engine off, of course, take return line loose, aim into catch pan, rotate pulley with my finger and fluid will circulate. The return line is a low pressure line usually held on with hose clamp at the pump. The high pressure line is a threaded fitting.
All that talking and I didn't tell you much? lol
Is the vehicle really over heating would be the first thing to address . If this vehicle was brought to the chevy dealership I work at , hooking up the factory scan tool to see what the PCM - engine computer is seeing for coolant temp . Too see if the cooling fans work , too see what temp info . the PCM is sending to the instrument cluster . I know GM had stepper motor problems in the instrument cluster . The step motor is what makes the temp , fuel , speedo , tach , gauges needles move . Just replaced a cluster in a 2005 chevy cavalier , temp. gauge goes full hot after just starting the vehicle . The cooling fans should kick on at around 223 degress , do the cooling fans come on ? Given the amount of electronics on these vehicles , it maybe best to take it to a qualified repair shop . That knows how to test these systems . Without testing I would only be guessing as to what could be wrong , Unless your prepaired to replace a bunch of parts , because your going to get a lot of different cause's from on here . Testing is the proper way to finding the problem . If you don't have a scan tool to view engine sensor data parameters , temp sensor. At harbor freight they sell a
Non-Contact Infrared Thermometer With Laser Targeting. This will show what the temp is .

Sounds like it's your battery cables, either a bad ground cable or the positive cable. I would replace both and see if that fixes your problem. Your local auto parts store has them and that is a pretty easy job.
The wiper arm springs are weak,just grab a used set of arms as most ventures wipe great.People who stick their wipers straight up,usually when freezing rain is coming ,ruin their wiper arm springs and have less wiping pressure too, so have to replace their arms at some point. PEOPLE STOP LEAVING YOUR ARMS IN THE UP IN THE AIR,OFF THE GLASS POSITION.
You can't disable it ! It's software programmed into the PCM - engine computer . If it doesn't see an enable message from the BCM or theft module it won't turn on the fuel injector's . They do sell a by pass module on the internet. Do know for sure mite be able to turn it off with a factory scan tool .
Did they change the coolant temp sensor?
The one that sends the engine temp to the computer,not the one for the dash temp gauge.
If the engine has a leaky fuel injector it will start great cold but have trouble starting when hot unless you let it sit for awhile to evaporate the leaked fuel which would be around 2 hours.
Try holding the throttle wide open when it fails to start when hot,if that helps start it quicker then it is most likely a leaking injector.
Also when/if it starts hot look for black smoke from the exhaust as it starts
Sounds like a dry/failing bearing or power steering pump noise. You first need to try to track down where the noise is originating, and the most likely place is at the front of the engine.
I would start by listening with the hood up while parked with the engine running and the noise present, and seeing if it is coming from there. If so, the most likely cause is something connected to the belt - e.g. AC compressor clutch, tensioner, power steering pump, or generator. Can also be caused by the belt just slipping (warn out belt, tensioner not working properly).
