2001 V70 AC problem

sahdct · Post by **sahdct** » 07 Jul 2008, 20:33

After about a half hour of driving the ac just stops blowing. If you feel the vent they are very could. I manually crank the blower and it very soft. I can hear the suction of air taken in the the noise behind the glove box. It just getting out. The freon level is good. If I shut car off and get in it will work again. Shutting the ac on and off while driving works sometimes.

Any hints? Bad sensor or the blower? If so how do I fix it. My dealer tells me the usually thing, that it works fine.

Thanks,
Dave

have you tried replacing the cabin filter?

yes. I replaced the filter. I wonder if its some kind of sensor. After running the car for a half hour the blower to force the air out just isn't doing it. The vents are cold. The ac is not clicking on and off.

Hi, I repeat what I have been writing earlier in this forum:
I have seen in the Swedish Volvo forum a lot of discussions about this problem. Finally, one Volvo technician informed that on the left side of the evaporator it is a sensor checking that it is not getting too cold ( = ice) in the evaporator. Then the ice is stopping the airflow. If you turn the AC off for a while, the ice is melting and the AC is working for an hour again. Solution, buy a new sensor and change it. It should not be any problem to change it, just replace it. Price in Sweden as sparepart, 25 USD. It is placed at the left side of the evaporator. Loosen the panel above the pedals. The sensor is found up to the right somewhere at the evaporator. It is fastened by a espanjolett locking function. The lengt is appr. 3 - 4 inches.
After this information it has been at least a dousin of greatful Volvo owners
