Module meltdown
I just purchased a 2002 silverado Z71 automatic 5.3 with the push button 4 wheel drive. When I bought it the service 4 wheel drive light was on.There were no lights on in the selector switch. After reading this forum and many other articals I desided to replace the selector switch. It did not change anything. I then took the truck to a transmission shop that had the electrical equipment to check all the codes. They determined that the Transfer Case Control Module was bad. They said they could repair it for $800.00. That was a little steep for me so I looked up the proceedure to replace the module and found that it was not that difficult. So I ordered a Module and replaced it myself. I started the truck and the lights on the selector switch came on and the service 4 wheel drive light went off. I turned the truck off and completed some other work I was doing. A few hours later I took the truck for a test drive. In about 5 minutes I smelled something getting hot and all good lights went off and the service 4 wheel drive light came back on. Any ideas?
