Anything regarding fluid on the bottom of the car has to do with motor oil located in the engine oil pan . The next fluid location would be the transmission or torque converter.
The same circuit breaker feeds the driver door as well as the passengers doors . The wires inside the rubber boot from the body to the door are probably broke ,power or ground wire .Or the door module is bad . Are your familiar with electronic control modules ? The door functions ,windows , lock's , memory etc... are controlled by DDM - driver door module .
Door Control System Operation
This vehicle has five modules capable of performing door system control functions. Vehicle door system components (windows, locks, mirrors, etc.) are controlled directly by these modules. There is a door module located inside of each vehicle door:
• Driver Door Module
• Passenger Door Module
• LH Rear Door Module (LRDM)
• RH Rear Door Module (RRDM)
• LH Front Power Window Switch
Simple Bus Interface (SBI)
Each Door Module communicates with the other Door Modules on the SBI. The driver door module is the only Door Module that is capable of communicating over the Class 2 Data Line as well as the SBI.
Driver Door Module
The driver door module directly controls the LH Front door lock actuator, power window motor and the outside rear view mirror. The driver door module sends and receives messages received from the LH Front Power Window Switch to the passenger door module, LRDM and RRDM modules over the Simple Bus Interface (SBI) line. Also, the driver door module sends and receives message from other vehicle system modules via the Class 2 Data Line.
Pulling the door panel off an checking B+ voltage and ground for the module would be good for you to do , since you probably don't have a $6,000 factory Tech 2 scan tool to see if the DDM is communicating .
The driver door module has two main power feeds (high and low current), and two main grounds. The low power feed (battery 1) is used to provide power for the driver door module's logic and internal driver operation. The high power feed (battery 2) is used to provide power for systems that draw higher amounts of current (motors, lights, etc.). Operating current at the driver door module's battery should not exceed 3.0 amperes at battery 1, and 7.5 amperes (for 2 seconds) at battery 2 while the driver door module is awake, and 2.5 milliamps when the driver door module is asleep. For most driver door module functions, the driver door module will operate properly with a system voltage of 9.0-16.0 volts. If system voltages exceed 16.0 volts the driver door module will provide protection by disabling certain functions that may damage due to higher than normal system voltages.
What kind of manual do you have ? The info above is from a factory repair manual .
The fuse's ,circuit breaker for the door module are located in the rear fuse box , not under hood . PWR WDO circuit breaker 30 amp. , DRVMDL fuse 10 amp. The rear fuse box is located under the back seat . Watch this video ,different type vehicle but probably the same problem .
Dodge Grand Caravan No Power Window No Power Locks CAN Trouble
The most probable cause is a failed HVAC control programmer. However, it may also be a failed cabin temperature sensor, causing the programmer to think it needs to set max heating. You can try removing the negative battery wire for at least three minutes and then reconnect it - this should reset modules in the car and may resolve the problem.
I recommend you replace the vehicle speed sensor. The part costs only $20, and is easy to do it yourself. This may not solve the problem, but it would cost much more to fully diagnose the problem.
There is a temperature sensor that the ECM uses to activate the cooling fans, but a quick test is to simply turn on the A/C. The cooling fans must run anytime the A/C is on. If that doesn't work, then the temperature sensor is not the issue. If they DO run with A/C, but not when the engine gets warm w/o the A/C on, then it is the temp sensor.
Could be.
It depends on how much they charge per hour and which gaskets are being replaced. Northstar engines are known to leak.
You can get a second opinion over the phone from another shop if you know which gaskets are involved.
Does it have keyless entry , does it open with keyfob ? This is fairly complex ! It would be hard to diagnose from here ,need to hook up a factory scan tool to see if the switch signal is present at the ( IPM ) an see if open message is sent to the RIM module !
Rear Compartment Lid Release Circuit Description
When the rear compartment lid release switch is pressed, ground is applied on CKT 1576 (BLK) at terminal D5 connector 1 of the instrument panel integration module (IPM). The IPM will send a message via the class 2 data line to the rear interface module (RIM). The RIM applies ground to CKT 1344 (LT BLU), with the valet switch in the ACCESS position, voltage is applied from the ALDL fuse 4, through the TRK REL relay coil. The relay energizes, the contacts close and voltage is applied from the BODY fuse to the rear compartment lid release solenoid. The solenoid is connected to ground G402 via CKT 850 (BLK).
Theoretically yes. Antifreeze has a higher heat capacity than water. Basically, a liter of antifreeze can hold more heat than a liter of water. I dont think it would be enough to cause an overheat though
Always stick with what manufacturer suggests. I believe it's 5W30. But- Autozone or any parts store can look it up for u so u get what manuf. states. I wouldn't switch to synthetic either. Not worth the risk. Follow old addage: if not broke dont fix it!
