E36 323i Coupe – heating problem

[Frimley111R]

I had the thermostat replaced recently so now I have heat but, even with the fan on full, the airflow is very weak. Is it likely that there is a filter blocked or is there some other issue that I am missing?

If its got air con make sure the knob on the centre vent is turned to hot.

Change pollen filter. Pulled mine out a few weeks ago and the heat incresed ten fold. Was completely black and clogged with leaves and debris.

Its got climate control. Thanks for the advice, did a bit of googling and found that may well be the problemo:

Looks Like I have to access it via the driver's side lower centre dash panel. Fingers crossed....

Another odd issue it has is that if I turn the centre 'dial vent' (the dial on the centre vents, just at the bottom) to cold the air flows out quite well but if I put it on heat is slows right down.

Mine does exactly the same, now whether thats how it should be or not i am unsure!

Could be the final stage resistor unit needs replacing. Aka the Hedgehog. Not expensive (say £40 for the part) but a bd to fit unless you're a contortionist. Common fault.


ETA the symptoms your car is showing are the beginning of it failing.

Oh great! I'm just replacing the resistor pack in my Elise which is a 7hr job so it should seem like a doddle after that.

7 hours! thinks twice about investing in an S1

Should be 20 mins in the 3 series. Hopefully. Good luck.
