Stupid heater in my 240 only blows outside temp air. Used to blow so hot I couldn't tolerate it. All of a sudden... No more warm air. There's gotta be a simple stoopid solution to this and I'm sure one of you lovely folks knows what it is. Please do share!!!

 

Any change in the feel of the temp control slider? These are cable operated and occasionally the cable can break or work loose. Removing the kick panel on the left side of the console (by the driver's knee) will shed a bit more light. The heater valve can also stick shut and the cable no longer move it. Increased force just makes the cable slip in its holder without adjusting the temp.

 

Hey, long time no see.

How is your coolant level?

 

Probly cause the head gasket is blown. Asked about steel seal in another thread. Sheeeet....
