The a/c worked fine before i took the HVAC housing apart to change the heater core on my 2001 Dodge Durango. It took me awhile to figure out how to seperate the housing to change the heater core. As far as I know i put the housing back together correctly but now the dash will not switch from heat over to a/c. The a/c is fully charged according to my a/c manifold gauges but the dash doesn't seem to trip over. I am at a loss as to what could cause this. Any help would be much appreciated.
