Default No A/C in eclipse

My friend has an 03 eclipse and the ac isnt working. So he had me take a look at it. It was low on refrigerant so i evacuated the system and did a vacuum test which it passed. Then i recharged the system and it still doesnt work. The compressor clutch is engaged but the system isnt building any pressure. Both high and low side stayed at just under 100. Any ideas what it could be. My guess is a bad compressor but i want another opinion before he spends the money on one.

you are building pressure, so I would not say the compressor is bad. The high and low side should not be equal.

when the car is off should the pressure be close to the same as what the outside temp is. because it was pretty close to the same but with the compressor running. which leads me to believe the compressor isnt doing anything

sounds like you have a plugged orifice tube. your receiver dryer may have come apart and the dessicant balls came out of the bag and plugged the tube.

I love reading these answers.

If you are certain the clutch is engaged, and the pressures are the same, your compressor is junk.

And, I would LOVE to know how it passed your "vacuum" test

ok, thanks. Yeah the clutch is engaged. I just wanted a second opinion before putting a compressor in it. As long as the compressor isnt leaking i dont see why it wouldnt pass a vacuum test. It reached the set vacuum and held it for the set time.

Oh, so you used a micron gauge to make sure you weren't loosing vacuum? Because of all the o-rings and rubber hoses on cars, pretty much every car fails a vacuum test when using a micron gauge. Use nitrogen.

I used the automatic a/c machine we have at the dealer i work at. Im not sure how it determines if it passes or not. I know it wont pick up on really small leaks but will find the bigger ones.

100psi is pretty much ambient temp. It's not building pressure.

Plugged orifice tube would build high pressure on the high side and go into a vacuum on the low side.

If you don't drop a few inches of vacuum after 30 minutes, it's pretty much considered a pass.

Make sure the compressor clutch is engaged. Try turning the clutch by hand. The valves or shaft in the compressor may be bad so turning it by hand should be easy.
