Hi,

Thanks. But how do I tap the relay (where & How?) Please help me.

Also the Regulator part number is not the one you specify, its BEHR (with Merc logo) is 210 820 62 10 instead.

I want to confirm when I say Blower, its the the Blower in the car engine but the Air Conditioner Blower, which is located beneath the Passenger seat dash.

Hi,

I manage to open the fuse box & I see there is a hidden half of the fuse box, the RELAYS. But which is for AC? I suspect the one on top (yellow)

If its a faulty control unit & I bought the car new in Aug'2001, do you think it will still be under warranty?

I will be ashame for Merc to have such a bad quality. If its warranted I will not take the part apart

I have remove Fuse no. 4 & 7 for the Air Conditioner but the AC Blower continue blasting away. Does this conclude its the AC Control Unit Faulty & not the Regulator ?
