Hello all, I'm new here. I've search for my problem but I haven't been able to find any solution.

I'm having problems with a 2005 Grand Caravan sxt 3 zone climate control. At times the center seems dead, no lights and won't power on. I've tried disconnecting the IOD fuse and the battery. The control will work perfectly for a little while. When I shut the ignition and restart it looks dead again. The battery shows 13.00 volts off and around 13.75 while running. Everything else works fine.

Thanks.

Remove the control head and inspect the connections. If they look good, add some dielectric grease to the connector. If the problem continue replace the control head.

 

The connections look good. I unplugged and plugged in the connectors and the unit worked. Turn off the car and start it again and it was dead. It's like it's throwing a code, but it doesn't die when it's already working, just when the car is restarted.

 

Well, my wife said the hvac was working today. But the temperature gauge in the roof console isn't working now. Any ideas what's going on?
