Hello All:
I have tried many things and am still having issues with my 4x4 not engaging. I have read through about 90% of the posts and would really appreciate any info you guys can give me. So here is my story:
1. 4x4 worked wonderfully for about 6 years into ownership of the truck. I was more than happy and pleased.
2. Bad snow storm hit 2 years ago...I discovered that I had 2 wheel drive only and got stuck. Needless to say, being stuck in NYC during a snow storm can be a terrible experience. So, after having parked the truck in the same spot where it was stuck, I was less than happy and wanted it fixed.
3. I read the forums and there were suggestions that it may be the transfer case motor. I went out and found a working one at a salvage yard. I paid 200 to have it installed because I don't have a lift nor a spot to work on my truck safely. The motor was changed and like a kid at Christmas, I pressed the 4x4 button and nothing happened.
4. I read some more and it was suggested that it may be the 4x4 control module. I bought one from Rock Auto. It looked like the right part and even plugged into the wiring harnesses correctly. However, when I started the truck, the 4x4 low light started blinking. I though that it was a good sign. Sadly, as soon as I pressed the brake fuse number 23 blew, and locked out the shifter. I took the truck to Autozone and they "worked" on the truck. So $175 later, they said that they had no idea.
5. I removed the new module and plugged in the old one. When I did that, I noticed that the 4x4 lights on the instrument cluster lit up and the truck was able to be driven. I pressed the brake shifted into drive and off I went in 2 wheel mode.
6. When I press the 4x4 high button, the 4x4 light illuminates on the instrument cluster, but 4x4 does not engage. When I press 4x4 low, the light on the 4x4 low button blinks.
After the 4x4 light illuminates on the cluster, it stays on for about 2 minutes, then turns off. I am sure it is because the truck does not actually go into 4x4 mode.
7. I have spent 2600 on an engine rebuild and 2000 on a tranny rebuild about 3000 miles ago. The truck runs awesome and I am really happy with it, I just want the 4x4 to work.
Any help would be really appreciated. BTW the module I got from Rock Auto did not cause the 4x4 lights on the cluster to come on...all it did was blow fuses. So, I am guessing I lost 200 on that part, oh well.
You can email me if you have followup questions.
Thanks in advance.
