I'm installing the rear blower motor. Mine only as one outlet. I'm assuming this is because it had air conditioning.
 The parts book only list one blower motor, but it has two outlets, although the parts number on my blower matches the one in the parts book. (IMG:style_emoticons/default/confused24.gif) 914 rubber shows a blower with two outlets as well, but different from the parts book??  |

You have to set the dash controls so the fresh air box is closed. Check the wire on the red handled lever. The lever must be fully raised to activate the fan and it also opens the Heat valves. The aux fan is only of any assistance while idling. Capping both J tubes, decent heat exchangers and a sealed ducting system will provide ample heat.

When the heat control lever is raised the initial motion pulls the cables which gradually open the heat control flaps at the heat exchangers. When the flaps are open the last lever motion makes contact which turns on the fan in the engine bay to boost the airflow through the heat exchangers. |
