I got no movement when I put 12v to the wires and trying to spin the fan by hand is a challenge so, I think it’s dead.
Now what to do? I see pelican parts has a Bosch motor only, a Porsche fan+motor assembly, and a URO fan+assembly. What have you folks done for your heater blower rebuild and how has it worked out? (IMG:style_emoticons/default/poke.gif) I’ll say up front, I’m biased toward the Bosch motor for two reasons: 1.) It’s a Bosch 2.) I’m not excited about a plastic fan in the engine bay. Thanks, Van |

Not an expert....but what about the cooling flaps that are operated by the thermostat?
If they are locked open than no heat or at least not much heat will go into the cabin. Am I correct or way off base? |

Am I correct or way off base? just means the car is slower to warm up. won't effect the heater operation once the engine is warmed up. the bleeds for the heater are way down at the bottom of the fan casting and rectangular in shape. hidden behind the sleeve joint for the air duct joiner to the heat exchangers are little flaps (or should be). they need to be free to move. air flow blows them open. |
