Good morning,
The problem concerns BMW E46 Sedan, 320i, 2000.
After switching the key in the ignition switch to the second position - the blower starts, ignites the control and everything looks OK. The blower operates without interruption and stably, reacting to changes on the air / air conditioning panel.
After starting the engine, the blower switches off after 3 seconds. Then it turns on for about 1 second, but only if I run anything else that requires voltage, such as lights, turn signals, rear window heating or air conditioning.
Since the problem appeared:
- I replaced the air supply panel by connecting another one - no changes
- I checked all fuses, not only those responsible for the air supply - they are all OK
- I changed this relay (click) with horn relay - unchanged. The horn works, so I bet that the relay is operational.
Some people suggest me to replace the hedgehog (blower resistor) - but it is 200 PLN, and the standard symptoms of a fallen hedgehog I found on the internet do not match mine.
Does anyone have any idea what to check / do, in addition to the possible replacement of a hedgehog?
