W203 AC Blower Motor Spins and Stops
Hi,
I have a 2001 W203. The other day its AC Blower started to run even when the ignition was off. After a while it turned off by it self and then it never worked again. I went to the agent and they said that its the blower motor regulator that i need to replace. I bought a used regulator and fixed it to the motor. But the issue was not resolved. Once I turn on the AC the blower motor will randomly spin and within a second it turns off. In about another 15-20 seconds it starts to spin and again turns off in a second. This happens repeatedly.
In order to confirm that the regulator i bought was not faulty, i checked with two other regulators. But the result was the same. I have checked the fuses related to the Blower Motor, they are all fine.
Appreciate your ideas on this.
Thank you.
Regards,
Madhurya

I know it's a bit late but I have the very same problem and I've been visiting many ''electricians'' and ''mechanics'' and none of them figured out what the problem is. If you found out and resolved your problem could you please let me know what it was because it's so damn hot, I need that AC.
