Well not my car. But my girlfriends '88. Initially the heater wasn't working so she took upon herself and checked the fuses,they were fine so she bought a new blower motor and replaced hers. Still didn't work so by this time she came to me and I figured maybe her logicon was bad. So I swapped mine for hers and wallah I could hear the blower motor kick on! But now no air will come out of the vents? It sounds like it is but none of the vents have any airflow. The vents don't seem to be stuck closed because whenever I hit a new setting I can see vents close and open. So why isn't the air coming out of anywhere? Can't seem to figure it out and she really needs heat to defrost her windows since she works at 4am almost everyday

 

the logicon works fine on yours no problems? bad wire or something not making the vents open? idk if there is a relay or anything that could be messing with it look at the wiring diagram and see how they work
