a/c was working perfectly.....ran the 'swamp lake trail' on the way home turned on the a/c......no air in the front vents...only in the windshield ducts..... what can i look into .. [same thing happened to a wrangler i sold..ouch..it was expensive to fix.] hoping the xj is a simple fix!! '91 w/auto trans and a 4.0 H.O..

You have a vacuum leak that is preventing the heater system servos (which are vacuum operated) from moving the heater plenum doors to the dashboard vent postion.

You say you went wheeling. I would bet you damaged the vacuum reservior in your front bumper. It's a sausage shaped plastic tank located inside the bumper channel, and has one vacuum hose connected to it.

sorry,,,should have stated already had checked the reservior and followed the vac lines...they seam to be ok.
