I have a vol. 2 FSM for the 1993 pickup, it covers the chassis, electrical, body and A/C. I believe they have the same A/C system from comparing pictures. Does anyone know if there is a difference? I would like to use the manual to try to get my A/C working.

 

Same system as what? 3rd gen pickup?

Should be the same afaik, they didn't switch to r-134 until some time a bit later.

 

I forgot, mine is an 88 yeah 3rd gen
