  • 2004 CHEVY SILVERADO 33000 MILES
    I HAVE BEEN READING THE BLOG AND HAVE THE SAME PROBLEM WITH MY CLIMATE CONTROL, COOL AIR ON DRIVERS SIDE, HOT ON PASSENGER SIDE, HAS ANYONE GOT GM TO HELP OUT WITH THIS PROBLEM. I HAVE BEEN IN TOUCH WITH DIST. SPECIALIST TO NO AVAIL. HELP!!!!!!!!! THEY WANT WELL OVER $500.00 TO FIX PROBLEM.
  • I was told it was the accuator(sp) the 2004 GMC Sierra had a recall on the instrument cluster, I took my truck in and had that replaced, I don't recall my air getting hot on the drivers side since then. It probably wasn't related but thought I'd mention it. I've since sold my truck. :(
  • DIST. SPECIALIST # 866-790-5700 MAYBE IF WE COMPLAIN ENOUGH WE CAN GET A RECALL.

    There is a technical service bulletin to correct this problem. It is normally covered under warranty. Unfotunately, yours failed outside of the warranty period.
  • Did you try what i suggested in post #159? It only takes 15 min or so. I had the same problem and its been working for 2 weeks now. As for the fuse to pull it is labeled HVAC and is located in the fuse box in the engine compartment. Good luck.
  • I followed the instructions on this blog and it worked for me. Disconnect the battery and wait for awhile then reconnect. I had to do it a couple times and also realized that because I have a diesel I had to disconnect both batteries (duh!). Also, turn off your climate control before shutting off the vehicle and then disconnect the battery.

    It cleared up my issue, good luck on yours.
  • Isn't it kind of dangerous to hold your battery cables to get for 30-45 sec.?:(
  • Hello, I'm having the same issue w/ my ac not working and air only coming out of the defrost on my 03 chevy silverado. Did you fix your problem??

  • Just turned the heat on in my truck for the first time this fall and only had heat coming out of the dash under hard acceleration. The rest of the time it blew cold regardles of the position setting. Also, when i tried to put it on recirculate, the light flashed a few times and turned off. The temperature gauge was also way up the hot end and didn't come down. Any suggestions would be appreciated!

    Check your coolant level in both the overflow box and the radiator.
  • Thanks. I will do that and see what happens.
  • Topped it all up and everything appears to be working fine. Thanks!

    Glad it worked.
  • when you hold the cables together they are not connected to the battery. your just holding the cables together you dont have to try it but it worked for me. I got the idea from the tv show TRUCKS on spike tv. i have not had any problems since, did it about 6 monthes ago

    I have had the truck since new and it now has 68,000 miles.The noise began near three yearsuse and has been intermittent . I noticed a drop in cooling ability last year and I did add a can of r-134 this year. That made it blow much colder but the expansion valve noise did not change. It can be quite loud at times but is tollerable( stereo volume up).When the truck was under warranty the dealer dealer told me it could be replaced ( the valve) but it would end up doing it again. I'm wondering if this is common with the 99's and has anyone with this problem been solved ?
  • I was driving along the other day with the A/C on and started to smell burning wiring (kinda of hate that smell being a commercial pilot) and a little smoke. Then the blower fan stopped working. i pulled over and looked under the dash and the four wire connector going into the fan box was smoking and melted...so were the wires for about an inch back from the plug.

    I am taking to the dealership that I bought it new at on Monday, but am asking you experts if their is any documentation of this being a problem? The dealership that I bought it at is one of those high volume stores and they have a reputation of being hard to work with on the service side.

    Any help would be great!

    I have never personally heard of anything like what you described happen. I frequent several GM boards none of which reports anything like above.

    If you find your dealership hard to work with on warranty issues, give GM customer service a call and they usually can refer you to another Chevy dealership in your area. With what you describe, I don't think that the dealship can question or deny warranty coverage as the results (burnt wiring) is obvious. Probably due to a ground condition somewhere along the wire.
  • I am also currently having this issue i have a 2005 sierra 2500 with 20,000 miles the thing is only used during the winter and my heat /ac does not work brought back to the local dealership where i bought it from and was told a bad relay caused the wiring harnes to burn up and was quoted 300 to fix i think that is b.s. it is obviously a factory defect i called gm cosomer service and they offered to pay for half but will not cover the whole repair. the tech at the local dealership said he sees this all the time obviously they have a problem.
