caravan climate control issue
 

I have a 2005 dodge grande caravan with the automatic climate control. In our -45 weather up here in Canada, my battery died and I boosted it to get it started. now my climate control panel is dead and my fan is blowing full blast and I can't adjust it on the panel. I checked the fuses in the tipim and they are all good. I replaced the resistor on the blower motor tho I wasn't hopeful it was the problem, reset the tipim and checked the codes on the dash nothing to indicate where the problem is. Any ideas before I take it to a stealership???
