Why does the AC quit working on my Tahoe?

Why does the AC quit working on my Tahoe?

Same thing happens sometimes on passenger side. At first, hot air would blow out of the passenger’s side while the AC was on. Next the AC would quit on the driver’s side and blow extremely hot air (hotter than just the heat). I can get the AC back on only by shutting off the vehicle.

How can I add refrigerant to my Chevy Tahoe?

Recharging the freon in your AC system is an inexpensive and easy first step to restoring the cooling capacity of your A/C system. Most refrigerants include a leak sealer that will seal small leaks in addition to filling the R134a refrigerant. The A/C system in your Tahoe consists of a compressor that is belt-driven, an evaporator and freon.

How much does it cost to replace AC actuator on Chevy Tahoe?

In AC mode, heat eventually comes out on drivers side. I had the actuator replaced by mechanic at a cost of $300.00 ($150 for the actuator and $150 for labor). New actuator worked fine for awhile now it’s doing it again. Anyone have any suggestions or instructions on how to install new actuator?

How much does it cost to fix a Chevy Tahoe heater?

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code (s) stored in the HVAC control module should be available to assist with diagnoses. The average cost for a Chevrolet Tahoe AC Diagnosis is between $53 -$67.

Why is my blower not working in Hi ( 5 )?

The usual failure of the resistor pack is if it works in HI (5) but not in any other mode or just a few modes. When you switch to high,the blower motor relay coil circuit is grounded and voltage is now applied directly through the relay to the blower motor; bypassing the resistors. So, I would look to see if the relay is ok.

Why is my Silverado Sierra blower not working?

Additional Info: The resistor makes a clicking sound when the control knob is turned to setting five. Another thread suggested that the contact plug may be burnt and need cleaning/replacing. That would restrict power flow. Got the same problem with mine on 2nd highest setting, gonna look into it in spring.

Why is the Freon not working on my Chevy Tahoe?

Those readings indicate low and no compressor activation. Here’s what they found, when they measured the pressure they said it was 11 PSI on the low side and 100 PSI on the high side, with the engine idling at 2,000 RPM. So basically low on freon.
