AC makes funny whirring noise- bearing gone?
my AC is having some issues it seems.
So when it first starts up, it's making some whirring noise.
At initial start up, sometimes the AC works no problem. But then if I pull up to a stop sign, the AC basically stops blowing cold air.
Once the car starts moving, cold air starts again no issue.
If the car is hot - been running for a while, like 3-5 minutes, no issues with it at all. The occasion "whirrring sound".. and not the AC condenser fan whirrr.. sounds a bit more like a bearing..
so from this dianosis, Im thinking that the belt that drives the compressor is running into resistance.. E.g. the bearing for the compressor is giving resistance to the belt so it's not turning freely.. except after it spins for a while i guess it losens up and starts to turn no issue.
1) is this possible to lubricate? do you think it would help?
2) or would this be a more serious problem and require replacement?
