1999 Chevrolet Silverado 1500 - Answered Questions & Fixed issues


What is the CODE for.? The radio anti theft code.? I know that with my old Honda Accord the dealer had the code archived in their system. I changed my battery and had to have the code to put in the radio.. I called the car dealership that sold me the car. All I had to do was give them my information and they looked up the code ID..
I would imagine that GM automobiles work the same way. I hope this helps you..

On the steering wheel is the hand controls. Scanning is stuck because of dirt or something. Push the buttons, blow out dirt, wash it off. Mine worked fine after that. (How annoying up til then though. Hope this works. Russ Werth Bowman ND

drain the oil from the front diff and check for metal flakes
If you have flakes --diff problems
if the oil is clean then look else where --like cv joints or "U" joints in drive shafts

Just for fun,clamp off the heater hoses,just squeeze them flat in place to stop the hot coolant flow through the heater core.Take it for a spin and see if the a/c stays cold.Sometimes with increased hot coolant flow through the heater core with increased engine rpm (driving) and a leaky air flow door in the a/c heater assembly,it can be hard to keep the a/c air cold.

This is an extremely difficult problem you have the biggest issue is the door won't open .I'm guessing you have a key less entry system if so can you hear the motor move for the lock in the door dose it have power dose the window work up and down .
This will tell you if the problem is electrical or mechanical if the motor is bad you will hear nothing if the clip broke or popped off.it will make noise.
Worse case you will have to take the other door apart take a close look at how it works then drill a hole in the broken door from the inside at a spot ware you can talk a screw driver and manually pop the lock open.
Well I didn't say it would be easy but if you look closely anyone could do it.

The ABS unit should have the connection IDs embossed into the casting at every line connection.You are going to HAVE TO determine every connection line going to every component to make this work.

This will set C (chassis) codes. You need to start there as the encoder motor (what performs the electronic shifting for the T-case drive modes {4-hi,2-hi-4lo}) will set codes that will enable you to quickly confirm if the encoder motor is indeed the problem. This is very common given the age of the vehicle.

It is likely that you'll need to replace the temp door actuator, more likely it is bad than the temp control.

Number one you didn't get Freon in your charge. So if you paid for Freon which is super expensive you got ripped off. It takes r134. And just cause you. Charged the system did you have the system tested. If not tested by a good hvac shop you may have clogged filters or other issues including your bad controls. Also it may have leaked out again if there is a leak

If you have an autozone in your area, take it there. Ask them to plug in the obd unit and diagnose your issue. They can give you a printout of what the issue the obd is seeing, can sell you parts, and even show you how to replace whatever.

Google door panel removal tools and you will see items that look like small crowbars. They slide between the panel and the metal and pry the fastener out of the metal. You can also watch videos on the process on you tube.
