    I can not turn the AC on until I shut off the engine and restart.
  • My 2008 Silverado sometimes when AC is on, the unit swaps to defrost with heat by itself and vice cersa when the heat is on. Anyone know of a fix for this, Thanks

    Hello everyone. I'm hoping you can help me. I don't have the money to take it to the shop. I'm going to try and explain everything as well as I can. So I think it's the A/C control panel. Now here's why when I turn my A/C off when it was working the two little lights indicating the A/C and the little recirculate arrow would either flicker away or stay on. I would have to wiggle the off knob for the lights to actually turn off and stay off. Now when my AC went out I seen on the panel those two little lights flickered and then off my AC went. It only blows out of the two side vents and the floor vents. Earlier today I did discovered that when I turn AC on it'll blow out of the main vents in the truck for a second and then go back to just the side vents and floor vents. I pulled my AC control panel out and there's little blotches of old soda on the circuit board from when my mom had the truck and spilled soda inside it. I've noticed that when I drive around and I have the AC off and the A/C button "off" and the recirculate air button "off" that when I drive around I feel air coming out of the main vents so that tells me the motor that opens and closes the vents is working. Oh and it also doesnt blow cold air it blows just whatever temp is outside even with the AC button on and the AC temp set all the way to max and cold. I'm basically stuck and I don't know what it could be seeing that my AC system is new. It's only about a year to 2 years old max. Sorry if I'm breaking any forum rules. I'm new here. I think that covers everything that I've found.

    Thank you guys for any help!

    When remote starting 2014 Silverado, the Heated Seats do not start. Outside Temperature was about 45F. Also, A/C was off. Dealer confirmed that the configuration settings were correct. Anyone know what the Outside Temp Needs to be to start the vehicle A/C and Heated Seats?

    Hi pclay,

    Generally, if the vehicle has heated seats, the heated seats will turn on during colder outside temperatures and will shut off when the key is turned to ON/RUN. When it is hot outside the cooled seats are cancelled when the ignition is turned on. The heated or cooled seats will not turn on during a remote start unless they are enabled in the vehicle personalization menu. You can find more on the heated seat function in the vehicle manual in Chapter 3-9. We hope this information was helpful to you. Please let us know how everything goes.

  • Our 2007 Chevy Silverado classic with dual climate control is having a problem. The heat mode only comes on when the control knob is set at 90 degrees. If you move it down just one degree to 89, it blows cold. This happens on both driver's side and passenger side. It also happens with the AC on. Any ideas what the problem is?

    I'm brand new here, first post....unsure of protocols, will try to be brief
    i have a 2003 gmc sierra 1500 5.3 club cab 4x4
    all fan / direction controls seem to work properly, climate control for passenger side works ( tempurature will change when told to), but drivers side is always cold regardless of climate setting
    On RARE occasions, the driver side will actually work and blow warm air, but very RARE.
    Attempted repairs: removed dash and the component modules to check and clean all electrical connections, re-booted the computer ( disconnected / reconnected)
    the module lighting is not working ( doesnt light up with dash lights at night)
    If anyone has experienced this or similar problem, any help or advice would be greatly appreciated. Toronto weather is starting to get just a bit chilly now!
    Thanks again.......anxiously awaiting any help

    I have a 2000 Sierra 2500 6.0. The ac works fine when the truck is first started and will continue working while sitting. One I start driving, the air warms up to basically outside temp and will not cool again until the truck is turned off for a little bit. When driving when it's not working, during summer or winter, even with the air off, it blows VERY hot air. No leaks and coolant levels are good. Any ideas? Thanks
