2002 WRX. Just started to notice this when it started to get cold recently. I have had the heater on before, with no issues. Basically when I go to turn the heater on, I get a nasty squealing noise from the front of the engine (outside of the car). It sounds like a pig is getting slaughtered. This used to happen on my Civic when I turned on the A/C. Same noise. Anyway, it only seems to happen when the engine is cold. Once it warms up the noise goes away. I popped the hood and tried to figure out where the noise was coming from. I pinpointed it to here: Has anyone had a similar issue? Maybe it just needs some WD-40 somewhere. Although, I'm guessing the cold weather has something to do with it, but then again I don't turn my heat on that much in the summer, so who knows. Thanks in advance for the help.
more than likley the AC belt. I suspect you have the HVAC setting to combo Defrost and Floor heat or just defrost? That setting will start the compressor as it's aprt of the system.
Good call, I do keep my defrost on a lot of the time. Was wondering why it would be coming from the A/C. Thanks for the quick response guys!
