Question about 2003 Chevrolet Blazer
I have an 03 chevy blazer, when I turn on the AC/Heater, it makes a noise that sounds like grinding almost and stalls the car making me restart it, any ideas on how i can cheaply fix this?
Sounds like your A/C compressor is seized up and stalls the engine through the belt train when the compressor clutch kicks in.
Try turning the compressor by hand (not from the pulley but from the front part (magnetic clutch), if you can't turn this by hand, it means the compressor is seized up...
As for fixing it, the actual fix would be to replace the compressor assembly, but believe me, that is usually not a cheap fix...
If you want the cheap fix, find the 2 wires that go to the compressor clutch (there is usually a plugin close to the compressor), unplug it and/or cut the wires and secure them to make sure they don't short out anywhere, or even better find the fuse for the A/C and take it out. Of course then the A/C won't work, but the clutch will not kick in and stall the engine...

Well I may need more information, but if something electrical loaded your engine to the point of a stall, i would expect fire soon. So most likely the fan motor is eliminated.
Now the A/C compressor, damaged and refusing to turn may be able to stall an idling engine, with todays cool serpentine belts... (In the olden days a belt would burn through and come off.)
The cheap solution to this condition is to turn off the car, and CAREFULLY unplug the compressor's electrical connection. Securely tie the wires out of the way, and test again...
You may want to consider repairing it, however, because the principle of refrigeration is a KEY COMPONENT to defrost in the winter...
Why? Because everyone knows a car air conditioner pulls moisture out, right? That crystal clear water that leaks out under air conditioned cars....
WELL, in the winter, rainy weather for example, is moisture. ....No remove moisture and no defogg.
