Question:

looking for wiring chart for 1991 GMC Jimmy. Windshield wipers wont work?

The windshield wipers won‘t work and I have replaced the fuse. The washer fluid won‘t work nor will the cruise control looking for alternate way to get wipers working.

Answer:

I am a big fan of more air. More air means more power. If it were a gas burner it could be a little to much but that diesel can handel just about as much as you can give it! Good luck
you can never allow too much air a diesel does not have a throttle body and will benifit from more air, that's why the turbo is there to pump more air into the engine air to fuel ratio is not the same as a gas engine
There is nothing available on line unless you subscribe to an automotive database. HOWEVER-- you can go to the library and find just exactly what you are looking for. It won't cost anything, and if it is on the computer you can even print it out and take it home. Or, you can go to the parts house and purchase a repair manual for the little pick up nd then have ALL the information for nearly all the repairs you are likely to attempt. They run $20.00.
