Hey all, so i finally did the heater in the jimmy. Wasn't half as bad as I thought it was going to be actually, dash came apart pretty easily, just bolts, screws and connectors. Now the only issue I am having is

1.) the truck doesn't seem to want to heat up. It never gets past about 130 degrees when fully warm. Thermostat seized open?

2.) the interior lights don't seem to want to work. Fuse is fine, but none of the dome lights work when you open the door. Not even the overhead dome lights work when you hit the switches for them. Any ideas? I am pretty sure I didn't miss any connectors, as the dash lights up and everything else works perfectly. Anyone?


^ that icon is really stupid lmao

 

Sounds like stuck thermostat, lights, dont know override maybe?

 

hmm.. never thought about an over-ride before. I'll have to check that out, good thinking

 

Dome light override button next to headlight switch. may not be on all models

 

I already checked that. I am starting to think that the little switch by the door (which when released activates the lights) but that wouldnt explain why even the button domes wont work.

 

Check the lamps.
