Question about 2003 BMW 325
When you move vent direction control on heater control panel and use blower air is vented from windscreen vents irrespective of where control knob is set. Check shows that solenoid is moving control in heater but always returns to windscreen. Can solenoid control be accessed from engine compartment or does whole dash have to be removed to check.
I have replaced heater control panel but still have same problem
I just replaced the "Final Stage Resistor" in my 2001 330i. Fixed the probelm 100% !!!. I followed the instructions descibed found here and on other sites. A little challenging, mostly becasue I hate working upside down, but the repair went as descibed. If you're even moderatley handy this is a straighforward project. I'd say about 60 minutes to carefully remove everything and about 30 minutes to put it all back together. Beats $500+ at the dealer!

it's either a fuse or it's a bad blower motor, it could be a bad blower motor resistor but usually you'll get either high or low only, so if you have nothing on any speed, high low etc, and all the fuses are ok chances are it's your blower motor.

all cars have a recycled air weather its called max or just recycle its doing the same thing. So if your getting cold air in one spot and hot in another it means your vents are not blocking where they are suposed to. It could be just a simple fix, by getting into the dash where your vent controls are and looking at the flap that tells air where it can and cant go. if its stuck then it needs to be cleaned and oiled. If the cable is corrodend clean it and oil it so it can move freely, or just reconnecting it may be the fix. it sounds like you are going to have to be adventurous, and play with the mechanics of your vents. Typicaly theres really nothing tough there to work on, just REMEMBER WHEERE ALL THE SCROOS AND CLIPS GO. I have forgotten where a few went in the past and had to listen to sqeaking noises till I took it apart again. There are vent seals wich are no more than the weather stripping you buy at the hardware store the 1/8 inch thick tape. You may need to thin it down with a razor, usually not. but it works great for fixing the seals in car heaters, because its the same thng just a different color. Which no one will ever see.
