I helped a buddy replace his a/c condenser (inside the large black box in the dash).

We had to completely remove the dash to get to the box.

When we reassembled everything, the head unit no longer works, the center console switches (a/c, etc) will light up but no longer work. Also the gauge cluster lights up but does not work.

We were thinking we forgot a plug somewhere, so we dissembled everything again, but could not find anything that was unplugged.

We checked all fuses inside and outside, none are blown. Any ideas?

 

that is called the evaporter...I know most dodges/chrystler/jeep blend door switches/temp control switches are controlled by vacuum, are yours? if so, did you accidently unplug the main vacuum supply to them as far as the gauges are concerned its either got to be a harness somewhere or you blew something up, did you unhook the battery while you were tearing the dash apart?
