85 300SD Climate control woes
just finished reading and rereading what is on this site about my my CC system
some how i never seem to have the issues of anyone else here is the story blower doesn't work at all at any setting ever BUT checked the fan it's free and spins easy turns on when bench tested @ 12v there is a clicking in the regulator when i push the fan speed buttons there is some sort of deep motor under the windshield wiper blades in the engine compartment that comes on when the fan is set to anything besides full off i don't own a voltmeter so i havn't been able to check the output at the motor to wire harness hook up point all the fuses are fine (that i can find) the brushes on the fan seem fine the thing is, there was no intermittent state it was a very all-of-a-sudden thing funny thing is, my 82 300sd parts car quit blowing air this spring the day after i left on a long trip i havn't really bothered to figure out why on that one besides general thots, i'm leaning towards (though not looking forward to) it being the blower regulator any way to test it? i'll be trying to get my hands on a voltmeter later today ![]()

finally got ahold of a volt meter
at the wires that go into the blower fan, i'm getting (at best) 0.17-0.19 vDC but i am getting something when i turn the fan off, the volt meter goes to zero is this the blower regulator? the irony of course is that BOTH (from the 82 and 85) of my blower regulators are bad ironic but not really funny anyone know where to get a working used one?
