Replying to: garymiller (Aug 27, 2008 1:42 pm) There is a technical service bulletin to correct this problem. It is normally covered under warranty. Unfotunately, yours failed outside of the warranty period.

Replying to: garymiller (Aug 27, 2008 1:31 pm) 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.

Replying to: garymiller (Aug 27, 2008 1:31 pm) 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.

Replying to: dansyota (Jul 20, 2008 12:59 pm) Isn't it kind of dangerous to hold your battery cables to get for 30-45 sec.? Replies to this message: dansyota (Sep 28, 2008 7:18 am)

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! Replies to this message: obyone (Sep 25, 2008 10:20 am) nitro07 (Sep 26, 2008 8:41 am) nitro07 (Sep 26, 2008 12:33 pm) and 1 more...

Replying to: nitro07 (Sep 25, 2008 10:14 am) Check your coolant level in both the overflow box and the radiator. Replies to this message: nitro07 (Sep 26, 2008 8:41 am) nitro07 (Sep 26, 2008 12:33 pm) obyone (Sep 26, 2008 4:07 pm)
