XC90 A/C Problems


Asked by Aug 08, 2013 at 03:29 PM about the 2006 Volvo XC90 V8

Question type: Maintenance & Repair

Last summer we noticed our A/C didn't seem to be cooling as much as it used to.  We had A/C checked and were told by dealership that coolant levels were fine but battery needed replacement.  Replaced battery but no noticeable change in A/C.  This summer the problem persists.  We used to be comfortable setting automatic temperature to 72 degrees in 105 degree weather. Now we have to set to coldest possible (64 degrees) just to feel any form of cool air... and it still struggles.  I've noticed that it seems to work better when on the highway traveling at faster speeds.  However, sitting at a streetlight within the city we might as well not have the air turned on at all.  We've had the A/C checked again and all coolant levels are fine.  Please advise, as I'm tired of throwing money at this car!

Clean ur coils infront of the radiator

would this explain why it cools whenever you're at speeds exceeding 40 mph and doesn't cool when you're slower or at street light idle?

1.Using compressed air, Blow out the lint where the thermostat (grilled area just above thermostat control). 2. Then turn both thermostats to lowest temp, fan on Hi and run for 30 seconds, now both thermostats to highest temp, fan on Hi run for a further 30 seconds. Repeat step 2 each time you start the car over the next week and then monthly.
