The AC condensor fan in my son's car turns on when the AC is on and stays on, but turns off when you turn off the AC. I know it's supposed to turn on when AC is on, but it isn't supposed to stay on from my understanding, and when testing this on my other vehicles, it doesn't act the way it does on my son's car.
Would this be one of the following issues:
- fan relays (there are 3 under the hood)
- low or high pressure switch? I assume it's the high pressure switch, if the system was low on coolant, I would imagine the low pressure switch would keep the ac from turning on due to low pressure?
- The AC needs charging as the coolant is low on charge? The AC does blow pretty dang cold though.
Car is a 2008 Lexus IS250 AWD.
Any advice/opinions would be appreciated.
Thanks.
