I am up in Canada and it is staring to get a little cool. Turned on the heat in my 87 560sel for the first time in a while and it did not work. The blower motor is running fine as is the AC. When I turn the temp dial down from the blue to the red, the AC shuts off, the fan keeps blowing but no heat comes out.

As well, when I come to a stop my abs light starts to flicker and the braking at a slow speed pulsates really hard. I can't feel any pulsating in the brake pedal. If I am completely stopped and press down hard on the brake pedal the abs light will come on solid. Could this be my abs sensors or a rotor issue?

Any help would be great as it will be cold and icy soon.

The Dude.
