70 psi static does need a charge.find compressor relay, jump relay and compressor will start. add refrigerant,replace relay and a/c should work fine

SOURCE: 1995 deville ac compressor is not kicking on and

Most likely a lack of refrigerant.  AC Compressors won't turn on without a minimum of pressure (generated by refrigerant).  Your system needs to be charged.  Best of luck.

SOURCE: i have cadillac deville 1991. need new gas ac

the shop is trying to sell something not needed. i have done many change overs without changing anything but refrigerent ant adding they oil supplied in the 35$ change over kit offered everywere.some have many years and miles on them and are ok.the arguement the shops will give are well sir, your compressor will go out.not, and if it did so what change it when it broke. the orings will leak.not my first change over kit job was in 1999 and the a/c still works fine. so get the r12 to 134a kit at walmart it will work unless it dont work now wich would mean it leaked out or some other failure. if so fix leaks/repair system then recharge

My ac pulley is seizing up,how can i bypass it with my serpetine belt?

You will need to order an AC delete idler pulley kit that bolts in place of the AC compressor, there is but one belt for both with and without AC. A company called DORMAN auto parts makes these, contact a local Napa or Carquest for application catalog.

My cadillac concours deville say low refrigerant ac compressor off and tried to put some in is there a certain way to do it

Yes, if it is like my 1990 cadillac deville, you must first disconnect the battery for 3 or so minutes and reconnect it to clear the error message and to reset the a/c system so it will turn on when R134a is added under pressure.

Cadillac did that in 1990 so the compressor would not run without refrigerant in the system. It's a safety feature designed to save a compressor if there is a leak in the system.

If you try to add refrigerant without resetting the a/c system, then the compressor will not engage.

usally tearing belts is the ac compressor not turning or poorly. your tension could be going bad also alllowing the belt to flex and contact another object. you will need to block your wheels.open the hood. have a freind rev the engine in cycles for you to watch and see if the belt flexes or the ac commperssor is the cause

AC doesn't blow cold air on 95 4 runner. Can I check compressor

Well, for one with the truck idling, the RPMs should increase every time that the clutch on the compressor engages. You should be able to see it engage and disengage and the RPMs will change accordingly. If this isn't happening then you need to determine why. Have the A/C blower on low when doing this.

Ac problems lumina 1995

I have the same problem, I was told to check the A/C pressure sensor built in with the compressor. disconect it and do a resistance test, it should give you a reading of almost infinitive , if it gives you al OL reading then that needs to be change. this is according to an expert.
