There is a low pressure switch in the circuit which is what cycles the compressor during normal operation. If the system is low on refrigerant, the switch will remain open. It is probably located on the accumulator if you want to check it, but more than likely you need to charge the system. I hope this helps!

Blower not working on 1997 chevy blazer


Check the blower motor relay, usually located under the hood in a box, also check the fuse in the fuse panel for the blower motor. If both of those are good then you have a bad blower motor.

It is a 1997 Chevy Blazer. I looked under the hood their is no fuse box for a starter relay fuse. I am trying to figure out where it is located. The starter works but the car won't start. We replaced the...


IF THE MOTOR WILL START WHEN YOU JUMP START, THE BATTERY IN THE BLAZER MUST BE LOW. USE A D.C. VOLTMETER, THE VOLTAGE AT THE BATTERY WITHOUT JUMPER CABLES, SHOULD NOT DROP BELOW 9 VOLTS WHEN THE STARTER IS TURNING. THERE IS A CRANK FUSE IN THE INTERIOR FUSEBOX. & A STARTER RELAY UNDER THE HOOD. BUT IF THE STARTER IS TURNING, THOSE ITEMS ARE WORKING. THEY ARE ONLY TO MAKE THE STARTER TURN. GOOD LUCK, DRVOLT.

the dash sound's like a fuse, check the fuse box under the hood and in the door jamb on the side of the dash, also check your fuel filter and fuel pump, im betting on the pump because i have a 2001 chevy blazer that has had two replaced and it has 233000km on it!

The A/C relay is in the glove box behind a panel that indicate relay. There are three relays in there, the middle relay is the fuel pump and one of the out side relay is for the A/C compressor and the other is for the third brake light. Just can not remember which out side relay is the A/C so just swap the out side relays with one another. Good luck and hope this helps. Keep me posted.
