Blower Motor not connected


Recommended Posts

I was looking around in the engine compartment to see if I could see any obvious air leaks in the vacuum system that would cause my cold stalling problem (see past post) and noticed that there is what looks to be a blower motor. It's located in a black housing on the top left side of the engine. It looks like it hooks into the heating / cooling system for the engine. Pardon my ignorance as I'm new to these cars but can someone tell me exactly what this blower is used for. The reason I ask is the wires that go to this motor are cut off so obviously it’s not working. The car is a 77 911S and the original 2.8 engine was replaced with a 1983 3.2 litre. I’m just wondering if this blower is a leftover from the previous engine and not needed on the 3.2 L or is this blower used somehow during warm up and could be causing my problem.

Thanks for the feed back on this. You could be right about the year on the motor. I was told that it was a 3.2L so it very well could be a 84. Will any power Source do as long as it’s switched by the ignition? It doesn’t need to be controlled by a thermostat or anything it just runs all the time? I don’t want to cause any more problems with my electrical. I think now I have a bad battery or alternator. Came out this morning and had to boost it to get it going , drove to work it was fine when I got there. Came out after work and the battery wouldn’t turn the car over. Fun fun fun.

I have an '84 3.2 Li and the blower to which you are referring feeds the heating system (I have the automatic thermostat controlled heater between the seats and the blower kicks in when I engage the heater - to push the heat from the engine, through the heat exchangers on the base of the engine, and onward down either side of the car rocker panel area. Then there are two additional footwell blower motors to further move the air into the cabin (left and right side of the driver / passenger foot area respectively). I would think that the blower is only linked to the heating system / or when your engine reaches a specific temperature, it could activate to remove some of the surface heat.

Not sure this would be linked to a car starting problem though, as mine only engages once the engine is running and the temperature increases.
