Problems with air conditioner control

Has anyone ever had trouble with their air conditioner controller not wanting to come on. Mine has been doing it for a couple months now off and on. when I start the truck the controls do not come on and so neither does the air. It happened today and it is only 94 degrees and about 90% humidity so you know about how hot it was in the cab.

Turn your headlights on and off a couple of times and it will come back on. The a/c module/control is defective.

Check the vacuum pump to make sure a hose didn't come off. I had this happen to me once and the 4x4 also didnt work. Sad to say a dealer did some work for me and they interrupted the line and didn't see it was off . I didn't notice it until I needed to use my heating controls and wanted to use the 4x4. It is located (looking into the engine from the front) at the 10 o'clock corner of the engine above the right hand fender. In my case the defroster worked but that was it. It's a small 1/4 inch hose that may be loose or not connected. Hope this helps.

Very common problem: My 05 does this from time to time.

same problem here for me also, and at times, it's like the air isn't always as cold as the temp i set it to. i'll set it on 60 degrees and it'll feel like 70/75 and i'll go 2 miles down the road and it'll start getting down to feeling like 60 degrees. any answers/suggestions?

Change the electronic climate control in the dash will fix the problem, but turning the headlights on and off has worked every time for me.

funn enough, i've had this issue, 3 times in the 3.5 months ive owned the truck. For me, its when my new to diesel idiot-self forgets to wait for the glow light to go out in the dash. Everytime I come to a stop, turn the truck off, and turn it back on and wait for the light to go out, and then give it an extra couple of seconds and then turn over the ignition, i have no problem.

"Why do people go to a diesel truck video to complain about pollution. That's like yelling at somebody throwing a quarter in a wishing fountain, "YOU COULD'VE FED A BOY IN AFRICA!"
