While trying to get the radio back into place I must have disturbed some vacuum lines and who knows what; I followed the manual and got the a/c going good, except now when I hit "recirculate" the air comes out of the floor vent (cold). I checked all the lines and can't see anything wrong. I think I need fan blower switch because I have to play with the lever, just a touch here and there, to get compressor engaged. Also, maybe my imagination, but thought I saw a wisp of smoke from around the rear of the switch; could not make it happen, and nothing felt hot.
Any ideas?Attachment 143292
