Question about 1998 Volvo V70

1 Answer

Heather blows intermittent cold air

My Volvo V70 (2005) blows about 5 seconds of hot air (which I have it set to do), and then blows about three seconds of cold (outside?) air. The air speed is not consistent; it seems to blow hard then slow down, then repeat the cycle. It does this for hours, and the car in zero weather never gets warm. I have tried it on Auto, manual, recirculate, etc., all speeds and settings, it continues to do it. Help!! Larry

It sounds like you need to go to the shop. the blend doors control the air flow, heat, and distribution. There are about 6 to 7 motors in all. They most likely need to be recalibrated. There is also a possibility the Climate Control Module Software will need to be upgraded. There is a small chance that there is a bad blend door motor that is crashing the communication link between the motors and the module.

Either way it goes only the dealer, or mabey a very heavily invested independent shop.

Hope this helps.

Have same issue with my xc70 cold to coolish on drivers side and warm to hot on pass... slowly, with driving, pass side becomes cool. Slight swoosh sound from dash attributed to A/C is intermittent. Thought to be kinked tube or puncture? : (

Thoughts?

1998 Volvo V70 A/C Intermittent


I had exactly the same problem. When your engine is cold and off check the gap on your ac compressor with a feeler gauge, it should be between 0.3 and 0.5mm. If it is larger you need to re-shim which invloves undoing a nut on the end off the compressor and removing the clutch plate, then removing the appropriate shims (look like washers) then replace. The reason it blows warm after 10 minutes or so is because the ac compressor gets hot and the clutch gap gets too large for the electro-magnetic clutch to engage. Some people would say that you need a new compressor but all you need to do is a re-shim.
