the sensor for the low side on my ac is messed up. I had a leak and my brother in law fixed it but when the ac was turned on after he charged it it was cycling on/off like every 2 seconds so he disconnected the low side sensor and tied the wires together so the ac wouldnt cycle off when u turned it on. after about 2 months i replaced the sensor with a new one and hooked the wires back up but it still does the same thing. what could be wrong with it maybe the pressure is wrong but i am very sure it is right because i just put in a new compressor and charged it again i believe 40 low and 200 or 300 high not sure on the high. does anyone know what the pressure should be. it is a 93 with 134a. i want this fixed because i dont want to freeze the coils

Okay just saw your message heres my diagnosis:
If the pressures are normal on both high and low sides and your clutch is cycling rapidly its an indication of a few things that you should have checked out:
1 low refrigerant charge
2 partially restricted - condensor core, evaporator orifice, or a/c liquid line
Normal high side pressure is 150 - 250
Normal low side pressure is 35-40
with the a/c system off and the clutch disengaged you should be reading equal low and high side pressures and they should reflect ambient outside temperature.
Hope this helps!<a href=\"http://albums.photo.epson.com/j/AlbumIndex?u=4187730&a=31095602&f=\" target=\"_blank\"> 2000 Black Firebird Y87 </a> <br />K&N filter, Whisper Cold Air Intake, Cutout Exhaust;<br />3.42 Gears, LSD;<br />160* Powerstat, Removed Silencers, MAF screen removed;<br />Zex hyperformance Spark Plugs, MSD Superconductor Wires, Manual Fan<br />Switch<br />15.08@90.86 2.149 60ftComment

is the ressure #'s that pfirebirdrumble00 gave me for 134a or r12 because i know that 134a runs higher then r12 and i have 134a in my car or is that the range for both of them. i will have to check out those ideas that pfirebirdrumble00 gave me when i get off work today at about 5 if you have any other ideas or suggestions please post them93 3.4 w/K&N FIPK installed 1/13/04Comment
