Heater

[christian]

My 1996 BMW 328is will not blow hot air while car sits in idle. The gas has to be applied in order for heat to function properly. It works fine while the gas is being applied. The temp. control unit has recently been replaced and a new radiator. Any ideas? Thank anybody for help.

As I understand it, it's your heater control valve that needs replacing...it's sticking. But lets see how others weigh in on this.

Especially in view of your recent replacement of the radiator, the more likely culprit will be insufficient bleeding of air out of the coolant system. Turn the heater on full hot, and re-bleed the system according to Bentley proceedure. This is a common symtom for inadequate bleeding.

if you have to put the foot on the gas to get heat, then most likely your water impeller is faling, dont forget the factory ones where made of plastic, check that too.
