heat comes out from all ventilation positions

Hi - Dave here, contributing to RepairPal and providing expert advice since 2010. I am hearing that heat comes out from all the vents. I am assuming that you are suggesting that the temperature control except colder temperatures. But heat still comes out. If this is the case, there are multiple possible causes. The air conditioning system may not be producing cold temperatures, which means there could be a problem in this area. Inside the vehicle, the climate control system could be malfunctioning, allowing warm air to come out when cold is desired. Hands on inspection is needed in either case.
