96 Accord A/C question
The air blows warm, Compessor does not engage, I attempted to fill the system with r134 but the system will not accept any.
Im not new to cars, or A/C but I am to Honda's lol
I heard that there is a safty pressure switch on the comp that can go bad and cause the system to not fuction.
Any help would be great! Helping a freind with her car!

I have a 95LX, there is a pressure switch that prevents the compressor from running with low freon. I don't recall where...I'd have to look at the book, or search here. AC guys will short it out to get the compressor to run. Running it without freon is not good. I have worked on many Fords, actually ran 12v (jumper) to the compressor for testing, and/or to turn it on to accept freon. AC stuff can be real simple, if it just needs a re-charge. It can get complicated if there is a leak (bad components) or the system vacuum has been broken. Let us know how it goes.

It is not good to add Freon if you don’t know how much is in there. It may be fully charged and you have no power going to the compressor. It will only take so much without the compressor engaging. There is a manual for a 1994 Accord on the DIY section of this forum and it should have the low pressure switch location and be the same as your year.

So,, put the correct amount, read the pressures and let us know , also chk to make sure that BOTH fans come on ,,,

When it's running properly, both fans will cycle with the compressor. Not simply full-time with the AC switch.
Both fans will also cycle with the fan-switch (high coolant temperature), regardless of the AC switch.

ok, got gauges. bypassed the pressure switch, compressor and fans working. reading on the low side is very high...... about 150. (the gauge set has a spot that appears to say retard? the needle is in this area and read between 120-350. the high side reads 150.
what do you guys think?

Did the gauges fluctuate when the engine was running with the a/c turned on coldest setting, air set to recirculate, and both front doors open? Did the pressure pretty much equalize when the engine was turned off?

and yes coldest, high, recirc, windows all down.

Are you sure that the clutch plate outside of the compressor pulley is spinning with the pulley?
As for your other question, the compressor is engage with voltage. There is a 1-pin connector going to the compressor. Does the compressor get 12V on the red wire when you turn on the a/c?
