I just bought a 1500 Club cab less than 30 days ago and it has developed a nasty wiring problem. I have lost the radio, dome and cargo lights, power mirrors and the OBD II plug. I have a check engine light and cannot read the code due to the loss of the OBD II port. I would say it has to be a common pwr wire but without a diagram I don't know where to look. I have checked all the fuses with a meter and everything there checks out. Does anyone have good helpful advice?

trrdk.

 

I had a 99 that did the same thing but I also lost my headlights. I know you said you tested all the fuses but double check the protected fuse inside at the door. I checked all mine with a meter said it was good. Ended up changing it and no problems from then on.

 

Check the fusemarked IOD.....

 

Thanks guys for the help. It ended up being the 10 amp guarded fuse. What a pain that was!!! Again, thanks for the help.
