final stage resistor

I recently purchased my second E46 in the fall of 2020. One of the first things I took care of was bleeding the cooling system since I was getting an intermittent coolant light and little to no heat (I believe this gave me heat again for a short period of time). The previous owner had stated...

Symptoms: When I first start my car, my AC will typically blow for a very short time then shut off. Then, a few minutes later, it will start and stop again. This usually continues for 10-15 minutes then blower comes on and stays on. It's not a cooling problem because air is always cold...

I have a brand new OEM Behr Final Stage Resistor (FSR) in the original packaging as well as a brand new OEM Bosch cabin filter for e46's. I'm not sure if these items fit other Bimmers? These were purchased brand new from AutohausAZ, and I never got around to install them in my car before I sold...

Hey, So I'm trying to fix the heater in my 325i. I have no control over airflow direction. I can hear the fan going, but (currently) it doesn't come out of any of the vents. I just finished a Final Stage Unit replacement, and there is no change. I'm going to be selling the car to a friend, and...

After researching the most likely suspects for this issue, I settled on the blower final stage resistor. Fuses are fine. At first it appeared that when the car was cold, it would turn on. Then after driving, turning the car off then on again - no fan. As I didn't have time to do this...

Just a general question. I'll be replacing mine soon. It's an interesting-looking bit of gadgetry. Are those heat sinks? What exactly does it do, electronically, and how does it do so?

Hi, I have a 2000 323i, manual. About two months ago, after a really cold -30ish C night, my car wouldn't start. The battery was really old so I replaced it and the car started fine for around 2 weeks. Then the battery died. I jumped the car and drove it for half an hour to charge it back up...

Ok, so my partner has a 2000 325i, which is starting to fail in various ways !?!? she is kinda attached to it and cash is in short supply. I on the other hand am a reasonably competant tinkerer lol but have not much ecperience with BMWs. the issues are as follows.... airbag light on dash - I...

Hi guys, Well, I got a 323i 2000 that I bought couple of months ago and it has started draining the battery. It actually does it once in a while i could happen every one week or maybe in a month. I thought it was the alternator and it is not because I replaced it for a brand new one. Also the...

Before I start, I'd like to point out that this DIY was carried out on my RHD 2002 325i SE by me in Essex, UK in August 2010. I am NOT a mechanic so my technical terms may be incorrect and my tools are basic. This is the second time I have replaced the FSR because the first replacement failed...
