Check for a slipping drive belt between encine crank pulley and AC compressor pulley.
Belt slipping? due to bad adjustment or glazing
Check fuses, common circuit
I think I had a similar problem with my 1991 Sentra. When the headlights were on, one of my wouldn't work. There turned out to be a loose connection with one of the wires.
Bad belt. Worn tensioner. Bad compressor.
you just need to change your oil sensor bro.
check a/c compressor and belt.
I am answering my own question - "It turned out to be just a loose connection in the swithch assembly".
Sounds like the freon is low. Have it checked.
The serpentine belt that operates the accessories is loose, or glazed and the squeel you hear is when an extra load is placed on it when the compressor cuts in. Tighten or replace the serpentine belt.
my water pump just went out and i thought that the squealing was my belt but turned out to be my water pump and the fact it was leaking anti-freeze. so yes
Someone tells me this could be to do with the starter motor
