Q: Truck squeals when heater is turned on

asked by on

I have a 04 chevy blazer, when my heater is on I hear a squealing sound coming from the belt/pulley area and I lose battery power. I have an new belt on it bypassing the ac compressor. Could it be the alternator, a dragging pulley or something else. And when my blinker is on the needle in the battery gauge bounces with the same rhythm as the blinker.

My car has 165630 miles.
My car has an automatic transmission.
