1984 Ninety Eight Regengy Brougham: You Like? Heater Question?

Hi. Just wanted to introduce my baby. (1984 98 Regency Brougham 307 Y)She was my grandmothers and has 62,300 miles on her.




One problem though summer is coming and my heater is always blowing hot air from the engine into the car through the floor vent in the center. Seems the vacum system for the doors in side may not be working correctly. If anyone has had a similar problem or can help thank you in advance.

Does the car have Custom or Tempmatic air conditioning?

It is all stock. Tempermatic I believe.

The flapper door for the heater box is right behind your glove box. Just take out the 9/32 bolts, and have a look.

I did the doors were working sometimes with help. I had most of the dash apart too. I don't know jack about vacum systems in this car. I was hoping someone would know how to work on that type of thing. A way to diagnose the problem maybe. Thanks. I am going to tinker with it for a while.

P.S. Any schematics I can get will help.

I'll see what I can dig up. Check your heater control valve for proper function in the meantime.

I'd check the vacuum lines under the hood. At 20+ years they rot away.

Damn that engine bay is clean

Update:
There is no vacum or air coming from the tube that controls the heater control valve. Must be whats on the other end that is the problem. Im going to keep diging.
