Re: Low tachometer reading
More news and hints for others concerning the blower connector problem. After I replaced the controller and the connectors the blower was running on abnormal low speed and sending some strange rough noise. I Finally went a Chrysler garage and they fixed the problem in 2 minutes. The connector on this new controller are incorrectly connected from Mopar, this is well know in this garage. They simply connected black wire to the red and red to black and problem fixed.
I am now slowly regaining my selfconfidence :-)
