Hello, new guy here.
I have a 1999 Silverado 2500 Extended Cab. When I turn the fan/air/heater knob on (on the dash), I instantly hear a noise under the hood. It's not a good noise like a motor running, but more of a whining noise. Any ideas?
Don't have much money, am unemployed, so am looking for a way to fix this. Not too mechanically inclined. By the way, no matter if I just have the fan on, the heater or the air, the noise is the same. When I turn the knob off, the noise goes away.
Please feel free to contact me directly (firstname.lastname@example.org).
I really appreciate hearing from you.
