2000 V70 Intermittant a/c operation

Post by rman »

you can have the a/c running for maybe 30 min and it just stops cooling! It will resume again in about 20 min. no matter what you do switch-wise on the dash. Seems to be excessively cold or have no temperature control when it is on. Any past experiences?

Welcome to MVS.
Have you had it serviced recently?
The "excessively cold" is a huge hint on what's going on...
I suspect that too much gas is in the system so the evaporator core freezes up...not allowing cold air to circulate...and when it melts you're good again.

Right in front of the windshield washer fluid tank is the low pressure port for your A/C gas...it has a cap on it that says 6nm. Take the cap off and use an A/C pressure gauge and measure how much pressure you have there (WHILE THE A/C Compressor IS ENGAGED...A/C running)....you should read less than 40psi...if you're above this, you need to bleed some pressure off at that valve. Good luck and let us know what you find.

To 'MadeinJapan', my aplologies! I just saw this in my posts. It wasnt my car at that time and the problem turned out to be the compressor clutch as the culprit for the mystery a/c operation the owner was experiencing. Some have solved it with washers or bread ties i've since read. in this case, a new clutch did the trick. I ended up owning it for 6 years after that (just sold it) and never had a malfunction there ever.
Once again
sorry for that no reply back in 2009
