Air Conditioning has equal pressure on both lines??
Im trying to get my airconditioning to work and each line (high and low side) has the same pressure on it. What could be wrong? Thanks

No,
low = 25-40 psi (depends on the car)
High = 190-250 psi (depends on the car)
low = 25-40 psi (depends on the car)
High = 190-250 psi (depends on the car)

If it is high on both sides I would think you have a clog somewhere. High I see around 150 usually, low like 30. You probably have the clog somewhere between the evaporator and the low side port.

thanks guys for your help. How would I go about locating the clog and removing it? I dont think the compressor is dead.

Uh.. there is no OT on a Honda they use TXV's.
and use freon? he doesnt have R12.. he most likley has R134A.. so call it refegerant ok.
what is the pressures? you need to be specific.
tell me what PSI and guess the temperature outside.

OH and BTW if you have equal pressures on both sides.. well its NOT a clog.. a clog will create a pressure difference so if your compressor is working(which I think it doesnt because equal pressures = not working at all or the TVX is not doing its job) then the system will have an accessive high on the high side or a very low on the low side.

ok if your outside temp is 90 and your getting 100PSI.. your compressor is not working.. verify that your compressor is actually turning on.
get a friend to go inside the car and turn it on.. then turn the fan on then press the AC button.. do you see the compressor clutch working? then check the pressures at that moment..if your compressor is working the high side will go up and the low will go down.

okay thanks, I think Im going to check the wiring as well. So we can rule out a clog at least for now until I verify the compressor is not running.

I found out that there is no current getting to the speed sensor on the compressor. If I bypassed this sensor to test the compressor would that screw the compressor up?

I didnt bypass the sensor after all. I found out that the wire from the power connector about half way down mysteriously was cut!!!?? I bet you it was the guy who put the condensor in. I bet you they would of told me I needed a new compressor too. SOB's Its really hard to find someone you trust these days. anyway cold ac now. thanks.
