My Barth is 28ft on P-30 chassis. Replaced heater core. Now need heater control head vacuum part. This controls where the heat goes.All help would be appreciated. Frank.

Did you do a search or previous posts?
This has been addressed different times, most recently within the last four months, as I recall. The control head (with very fragile mounting lugs) is a vintage Chrysler Corp. item. There are a couple vendors with replacements. I had saved the portion below for my future reference.
------------------------------------------------The plastic ears that mount this into the dash is broken and it flops all over the place.

I took a bunch of numbers off of this unit and called Chrysler. Pt# 3847742 is the push button switch and is still available. I am looking for the entire control or just the main mount. There is no part number on the cable itself.

I found one at RVSURPLUS in Elkhart IN

I just got off the phone with Cindy at
Acme Air inc.
79 North 10th Street
Kansas City, KS 66102
(913) 371-5373

Cindy was very helpful. It seems that these people bought out a company called ARA back in 1990-91.

The control head part# 4100277 cost $166.45

The cable part# 4103879 cost $15.33
(my cable says 0483173 but has been changed to 4103879 and is about 6" longer)

The heater control is still available from Chrysler dealers. The earlier posts have the new and old part numbers. I bought the push button assembly for $53.00. About two years ago.

This might be why I have not been able to find the cable. I should be able to go to the Chrysler dealer and use this number to get me a non kinked cable! Sweet
