trying to find the issue with my AC everything is brand new I mean everything the Hoses brand new dash control Comp,cond,evap etc anyway it blows snow when I force the clutch to engage it has the right amuont of coolant and lube in it. Ive replaced the relay for the compressor the pressure switches for the high and low, am I missing something could I have a broken wire somewhere? Does anyone have a schematic?

How about the one in the back of the compressor?

How are you forcing the compressor on?

What year?

I jumped it at the back of the compresor actually when my dhsh switches were messed up I put in a toggle with a relay and kicked the comp on like that. its a 1996 2 door

I thought the one on the back of the compressor was the high limit switch? The one in the accumulator was the low pressure switch IIRC.....

Which switches did you replace?

What are your pressures?

I replaced both of them, jumped both of them could never get the comp to kick on, I dont remember my pressure exactly the of guages I have I can only check the low pressure side and I am out of town at the moment I do remember I was dead center of the Green section of the guages, One thing I noticed was that the relay the top was loose so when I popped the cover off and could press the side with the cover which would open the relay and the comp would kick on, replace the relay and nothing so Im thinking it may be the signal wire coming from the dash head unit but I really just dont know. Also whenever I force the comp on the ac is ice cold........

Need to get that control head checked out I guess........

its brand new......

Like I said I literally replaced every part of the ac system lol I really think I have a wire issue maybe one is broken somewhere??.....

Time to start probing at the switches with a testlight to see where your disconnect is. You have checked fuse(s) right?

Of course every last one of em, I was afraid of that I guess if I have power being sent out of my control then its gotta be under the hood somewhere I really hope th break isint under the dash somewhere it will be a pita to trace if I loose power before it makes it past the fire wall.

I have a manual for my 95 as far as the wiring, but I suspect most of the schematics are a tad different, especially on the engine/ trans section..... If you PM me your email I will send ya what I have unless you already have a manual.....

I hope it is something out under the hood and easy to fix for ya!
