Question about Buick LeSabre
Vehicle has climate control
Posted by Anonymous on
This may also have been caused by mixing regular anti-freeze with dex cool, which causes the coolant to become like pudding and clogging the heater core. They are NOT compatible. It may need to be professionally flushed with the proper chemicals. If one hose is hot and the other is colder, the core is most likely plugged. Going through this on one now.

your water controll valve located at the right side of the engine near the extreme rear end of the inlet manifold may not be working properly hence the hot air .

you may have a failed blend air door motor/actuator. this part will regulate the amount of air from the heater core depending on the temp setting on your electronic climate control unit. if it has failed, it will be stuck at the temp that it was last set at when it quit working. it is also possible the heater core may be plugged up, but using the gm recommended dexcool coolant and flushing it out every 5 years, it should not be plugged up. you can pull the 2 heater hoses off the heater core on the passenger side of the engine compartment firewall and see if the heater core is the problem. caution-do not use a high pressure air hose to blow through the heater core as this could damage it and cause a leak!
