Why is my AC not working in my Impala?
Why is my AC not working in my Impala?
No more freon in the system, mine stopped working a while ago, had it filled back up and it worked, BUT I suggest that you have it tested for leaks before you fill it up, because it turns out that after 3 weeks I don’t have anymore AC that doesn’t sound good.
Why does my Chev Impala make a clicking noise?
I have replaced two last year on 2011 Chev Impala, 2011 model and another one this year. The repairman told me this is an issue with this model and he changes them a lot.

Why does my a / C compressor not engage when I Turn on the AC?
Anyway, the compressor clutch won’t engage when the A/C is turned on. The light on the switch on the dash stays on and the 10A fuse in the interior fuse panel is good…. Thanks!

What causes an AC compressor to not engage?
If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways. They can activate through a relay that’s energized directly by a proper condition of the low and high pressure switches.
Is it possible to fix an oil leak in an Impala?
No, you won’t be able to fix the leaks that way. The system runs too high of pressure, and the refrigerant molecules are too small, they will literally leak through the hoses if it weren’t for the oil in the system.
What happens if you run a compressor with no oil?
At that point you’re running the compressor with little to no oil. You may get it to accept a charge, but you may have already damaged the compressor before the system reaches full charge. NEVER try to bypass the low pressure switch. Doing so will force the compressor to run with inadequate oil and can destroy the compressor.

What should I do if my Silverado compressor does not engage?
Hold the can of refrigerant upright and slowly open the valve on the charging hose. The pressure of your can will force the gas into your system. While the compressor may engage immediately, allow the can to empty before removing the charging hose.

What should I do if my compressor clutch is not working?
If you’re not getting battery voltage, pull the compressor clutch relay and check for power and ground on the relay control coil terminals in the socket. Wiring varies by make, model, and year. Some car makers trigger the relay control coil ground through the PCM or ECM.
