Hi All
I havent done any work on the car of late, all water levels as they should be.
Passenger side in central air vents blowing cold air, drivers side blowing barely luke warn air.
The weather is getting colder and need to get this resolved.

How does the vent flaps controlled on these?

Thanks
Donie

 

The coolant going through the unit should be as hot as the rest of the coolant system as it is a bypass system - no valves.
Probably the Air mix door actuator
Hopefully attached PDF's might show the problem.
Try the two Diagnosis items first.

 

Thermostat could be stuck / sticking

 

Doesn't matter if it's stuck or open as the heater bypass circuit is on the block side of the thermostat

Confused now, when my stat was stuck closed, there was no heat either, but when on an incline it was blowing warm, maybe a bubble in there.
