madog7200 Posted September 29, 2018 Share Posted September 29, 2018 91 4.0... a/c compressor does not engage due to next to nothing power... does anyone have a schematic of the engine bay... I have generic ones in chiltons but can't decipher anything correct to my truck.. I can take pics and post pointing out where I do and do not have power if it would help?

HOrnbrod Posted September 29, 2018 Share Posted September 29, 2018 Recommend investing in a 1991 Factory Electrical manual like THIS one. 1991 was the first year of the Jeep HO's and has many unique electrical features not found even in the 1992 models. The best tool you can have if you do your own electrical repairs/mods. Link to comment Share on other sites More sharing options...
