Hey guys. I have a 97 328i, 5spd, 155k miles.

I have searched. But could not find a definite answer.

So my heater and ac doesnt blow very hard. It blows when im driving. According to other posts, its the heater core valve?

Also, another thing. I have a newer (March '09) waterpump, thermostat, housing. when the car is turned on, and the coolant resovoir cap is off, there is no circulation of coolant at idle or lower rpms. Circulation of coolant happens at higher rpms.

In the other posts, people suggested putting in new water pumps, but mine is new. (no overheating issues or anything). i also put in a new cabin filter

since i know this issue of no circulation of coolant, im assuming thats why i have no ac/heater unless im driving.

What do you guys think?

i really need opinions/suggestions.

On the climate system, what's the condition of the in dash fan?

2 common issues with the E36 fan speed are: a faulty blower resistor, but when this usually goes, the fan speed is stuck on high. If you have digital climate control, it is called the final stage unit, see in link below:

next, another common issue is the Climate Control Unit itself:
