Q: AC line cold, no AC blowing in car; heat blows really hot, only all lines have been replaced and fuse checked good

Could a dual climate control make blender flaps not open

My car has 100000 miles.

Hello. It is possible that your blend door actuator has failed. This is the part that controls your blend door. The blend door is responsible for blocking off the heater core when your A/C is on to prevent the hot air from coming through the vents. I would recommend having your blend door actuator inspected to determine if it is working or not. If the blend door actuator is not working I would recommend having it replaced by a qualified professional. A technician from YourMechanic can come to your home or office to diagnose why your AC is not working and make the necessary repairs.

Q: My ac went out can I bypass the ac pulley with a shorter belt

Yes, this is possible. However, unless it was the AC compressor clutch and pulley which failed, bypassing the AC pulley is unnecessary. Simply disconnect the wire to the AC compressor clutch and that should do the trick. The AC clutch...

Q: Why is my car blowing hot air and cold air at the same time?

The answer to this depends on whether you have switched on heating, cooling (A/C) or neither. In one scenario, for example, if you have not switched on the A/C system, but the A/C is running as confirmed by a visual...
