2000 Dodge Grand Caravan 3.3L w/ Rear Air

My A/C stated making a bad hissing noise a month or so ago and the front A/C was intermittent. The front A/C has completely quit now but the rear air blows fine. If I am running down teh highway I have ice cold air flowing through the front vents but no matter what I do with the switch, nothing blows. If I change it to inside air only I get no air at all. Do you think it would be the A/C relay, the blower motor or the dash panel switch?

 

Sounds like the dash panel switch. Probably not the A/C relay (because if it was you probably wouldn't get any cold air at ALL), possibly the blower motor (but unlikely). Grab a new (used) dash panel A/C switch from Pick n' Pull and see if that solves your problem. If not them it's probably the blower motor. Also check the fuse cables.
