Hello, I have a 2008 Camry 2AZ-FE 2.4L with A/C blowing warm air. I have a 2007 service manual and have ran what tests I can, but can not find the problem. I suspect the compressor, but hear they are very reliable on these cars...so I need to verify before replacing. I believe this car has the compressor without a magnetic clutch (2 wires to compressor & do not see relay for magnetic clutch). I have access to an older version of TechStream, but don't know how to use it. I have ran the following tests:

• Battery Voltage OK
• Check Engine light is not on/no codes show on OBD
• Pulled vacuum on ac, no leaks, added R134a, low & high side are approximately the same at around 75 PSI. The manifold gauges do not indicate that the compressor is engaging, but when I turn the A/C on and off the engine does increase the RPM.
• Checked the wires to/from compressor with ohm meter and it is within spec.

Any help would be GREATLY appreciated!

Thanks!

 

Depending on where the car was made it might have sight glass on one of its AC lines. Location is front of car slightly left (passengers side) of center (Toyota emblem).

If equipped with site glass, operate A/C on max cold, door open, high blower.

If compressor is working. Fluid in site glass will bubble up (foam) when compressor starts up then become clear. When compressor stops, fluid will again bubble (foam) then site glass go clear. If ambient air temps above 95F there may always be some bubbles in fluid.

 

Thank You toyomoho for the Reply! I have no sight glass on this model, but was able to verify that the computer was sending the signal for the compressor to engage, and since about 90% sure the compressor is the issue, I have ordered one. Unfortunately, the tranny has decided to not shift properly, so I'm probably going to try to address that issue before installing the compressor. If I remember, I will post back on the results of the compressor swap.

 

Thanks for posting with the update.
