Cadillac Repair: trouble w/ ac, cadillac seville sls, cadillac seville

Question
my 98 cadillac seville sls blows hot air on the passenger side but cool on the driver side

Answer
Hi Jose,

      The most likely cause is a temperature door motor that isn't working properly. You would need to remove the glovebox and lower dash panel to see the 2 motors and rods. Then with the engine running and at operateing temperature move the controls from hot to cold to hot and see if the motor fails to move or starts to skip somewhere in its travel. A little resestance to movement by litelt holding the rod might help. Then just replace the bad motor. Hope that helps. Bill
