The heater/AC control panel does not turn-on automatically after the engine is started occasionally, during this time none of the buttons are working and blank display. The only way I can get it turn back on is re-starting the engine, sometime it takes more than 1 re-start.
I thought the relay ? or the signal driving the relay has something to do with it. Where is the relay for the Heater/AL is located ?
I am wondering what your thought is or how to resolve this issue ?

This works when mine does this its happened 3 -4 times in the last 2 yrs. The First time we were on a trip it was hot I put the windows down when it got dark the lights came on so did the AC. So each time its happened I turn the light switch and then the panel works again ,and I thought I was the only one with this weird problem. Thanks for telling me whats wrong
Since the problem only happens occasionally; 1-2 time a month and it is not possible to re-create. How do you think Ford ESP will handle this intermittent problem ?. My ESP good till Sept 2011.
My dealer and I have a good relationship, I actually worked there as a service manager years ago. All I did was describe what happened and they replaced the control head under the ESP, I think it is a common problem.
I have not tried this. As when mine does not work I have been stopped at different places and I also read if you turnoff the head light instead of using the auto feature this does not happen. this does affect my windows and radio too. It does not cause this problem when using the regular light feature.

I have a 2006 motorhome on a Ford chassis, believe it's F53 or P53?. Anyway my blower quit working also. The strange thing is, when I turn the control **** to any position for a/c or heat the back lighting comes on behind the panel and nothing works. If I switch on my headlights the back lighting goes off. My headlights and other dash lights work but my a/c heat panel still does nothing?
