1986 Town Car - New Owner Vacuum Line Questions.....

Hi Bill -

I was just given a 1986 Town Car. It had a leaking heater core so I decided to replace it myself to save a few bucks.

All went well except for one minor problem. I have one small vacuum line under the dash I do not know where it was connected. I have the four other vacuum lines labeled and reconnected to what I refer to as vacuum actuators on the plenum. This fifth line I do not recall seeing at removal and I'm not sure where it goes. Any idea?

I'm not well versed in auto repair so please keep it simple ;)

Thanks in advance.

Joe

Hi Bill,

Thank you for your fast response and offer of help.

I've sent along some pics. The color coding on this particular vacuum line is black and white. It has a male grommet hole pin taped midway up the line to clip into a support hole. While once again searching for a connect point and taking pics I also found a blue electrical connection. Pic included also. I'm wondering if maybe it's an extra included in the wiring harness for a feature I don't have. Can't find anything to plug it into. I marked all the connections I took apart .... at least I can't remember taking apart any connections without marking them thinking its foolproof reassembly. I should know better than to think that ;)

The electrical connection is near the passenger side quarter panel area.

From your photos the vacuum hose in question is black with a white stripe. Ford uses that color hose for the HVAC Recirculating Door Vacuum motor. The recirculating assembly is located at the right side cowl area somewhat near the glove box area under the dash and up to the right. Locate that vacuum motor and plug the vacuum hose in to the nipple. If there already is a hose in at that location, that hose could possibly be plugged into the wrong vacuum motor.

Your photo of the blue electrical connector reveals no information to me. If you did disconnect it from somewhere you should remember because it appears to have the usual locking feature that needs to be released before it can be pulled and disconnected.

After you find the location for the vacuum hose you could operate the ac/heat system and check the operation to determine if that blue connector is part of the operation or not. For further HVAC vacuum and electrical information you will need to have and read the vacuum and wiring diagrams. We would have these available for you if necessary.

Sincerely,

Bill
