Top 20 2002 Chevrolet Silverado 2500HD Questions & Answers

Question edited for clarity. Question moved to model category. Did it have antlers? Did it go under the truck? My thought it that it either caused a fluid leak or it tore wires off the transmission casing. Transmission functions can be checked electronically with a professional grade scan tool computer. https://www.google.com/search?q=mobile+auto+electrician+near+me ..

Did you check for voltage at backup lamp fuse, use a test light. The actual diagram I copied was larger than this and easier to read. This must be a site issue, common to fixya. You could even use a long piece of jumper wire from battery voltage to light green trailer wire, to see if lamp will light. It would'nt hurt to use inline fuse, for testing. If lamp still won't work, maybe problem with trailer wiring. You could even use jumper wire to bypass the connector itself, same color wire?

It definitely sounds like the hydro booster. There are videos on YouTube that shows you how to do either. Depending on your skill level will determine which one you do. The main issue is bleeding the air out of the booster. It can be difficult. You will also need to bleed your brakes completely afterward. GMs are notorious for having the hydro boosters die on them.

if you had the rear wheels still on the ground in 4WD and it never drove the vehicle off the jacks or stands , you have a problem in the transfer case in other words the transfer case is not selecting WD

First get the gas checked to see if you have enough left to run on , if you don't have any gas showing it won't run the compressor ps go into your kwik fit garage and ask them to hook the A/C up to there machine and thay will tell you if the vehicle is leaking , empty and refill it

More then likely the problem is in the motor of the transfer case controller

Your chevy doesn't have one . Fords use one not GM vehicles .

Your Chevy doesn't have a inertia fuel cut off switch , Ford's do , not GM .

Any component that has a ground problem, why not try a redundant ground wire to see if components will work ok? A redundant ground hasn't failed me yet, I suppose it could, but, so far so good. In my database for ground distribution wiring, I didn't see a g200. I even looked at wiring for engine control diagrams, couldn't find G200. Is there a component that is having a problem?

replace the whole cable

This could be from current sensing from the voltage regulator. Get another meter and hook it up and see if it bounces. If it does, there is nothing to worry about. If it does not, the dash gage panel needs to be reworked.

your truck should only have 4 o2 sensors two upstream and two down stream. P0171=system too lean, P0174 I= bank2 sensor1 If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_4c166ba81493f541
