Question about 2002 Cadillac Seville
There is dual air conditioning systems (One in the front, and one in the back seat) Here is the problem, the one in the back works fine, the one in the front doesnt. No fan, nothing, not even a vent. The dealer willl gladly look at it for $150 and let me know whats wrong but there has to be a way for me to check it myself first. Does this car have 2 fans?
Does this car have 2 fans? YES . The blower motor control processor is probably the problem . Near the blower motor under right front dash .

There is a flat spot at the front of the right side (passenger side) cylinder head will have the last 6 of the Vin and letter code at the end of it for id purposes. You will see it looking down from the top of the motor.

there are two separate actuators for the rear system. one controls temperature and the other controls vents from head to feet. mine problem was the later. that acutuator for esv 2003 is 89018365. it is located just below third seat cup holder passenger side and can be replaced simply by removing cup holder. triangular shaped part with wire harness.
