AC help? Where to get info to trouble shoot?
I am trying to repair A/C. I have 134 in it (1995). Weird, as I am getting a VERY high suction pressure of 92 and a low (high side) of approx. 90 ! also!I tried to send 12v to wire going to compressor clutch (with a lead from battery + to wire but nada, zip. I thought that 12v would override the pressure switch and kick in the compressor clutch and therefore compressor..Any ideas? anyone now a good site for info re A/C troubleshooting? Thanks everyone, ! REally appreciate the help! Been looking for a MMax for a while now, wanted diesel, but the few I found (after 20+ yrs looking!! were rusted out and or 4500+!!! and still "rough", IMHO!! After reading most of this site:)!! in the last few days, I'm not sure whether to turbo this gas engine or just bite the bullet and go turbo with the upgraded engine 4d56...diesel..
