Hello everyone I got another question for y’all, so I have a 2011 crown Vic and the AC won’t blow at all however it does blow air when the car is moving and it blows cold or hot however I want it but it won’t blow at all stopped, this is what I tried so far I replaced the blower motor and the blower resistor and even the relay in my fuse box, I looked at my AC clutch and it activates, i even checked to see if stuff was behind my glove box just in case it was cluttered back there but nothing helped, I can’t figure it out
If you checked all the fuses and wiring, I think the BCM is acting up.
All my fuses are good and wiring are not frayed or cut up, how would I go about checking one of those bcm’s? Would it throw a code? Because it doesn’t have a fault code and the wires on the ecu isn’t messed up
you need a higher level scan tool for checking the BCM. Sometime the code does not show up simply because the manufacturer does not design for that. In the other words, you may not have codes for all the issues.
