Maybe you can help on this one Steve?


I hate to steal the fire from someones post, but I'm getting cold in the mornings to, and I've gotten no responses from my post. I've got an '80 300TD with the ole vertical pushbutton style climate control. I am not getting any heat at all coming out the vent in the heat or defrost mode. Any way to isolate the problem down to whether it may be the actual temp dial on the dash or perhaps the water control valve under the hood? When the engine is hot there is no warm cooling water going up to the heater core. The heating water pump is turning freely and working fine. The blower turns on immediately but blows cold air even in the max heat setting.

I'd appreciate any info you can provide Steve.
