Comfortron Power Module Reinstalled; BLOWER BLOCKAGE FOUND!!

I got the rebuilt Power module back from the rebuilder and reinstalled it.

It's been a while since i posted on this topic so I will remind those reading that the main problem I have been chasing is that i can't get air out of the AC or the heater ducts-even though the heat/ac vacuum solenoid is working. Today, I found out why.

I installed the newly rebuilt Module but it did not make a difference, even though I could clearly see the arm moving in response to the temperature wheel movement. BUMMER!

I don't know what inspired me to do it, but I took the power module off again and looked inside the hole in the heater plenum with the Power module removed. There I saw a flat piece of what looks like flat rubber insulation (about 7 inches by 5 inches), part of which had come loose from its proper place on  the plenum wall and had placed itself squarely in the way of the air path. I glued it back and tried the system: VOILA. I have air from the AC vents and Heat from the Heater. 

The frustration I have experienced over the last several months has made this triumph all the more exciting. Next up: Aim the headlights.

Excellent new Norman, very happy for you that the mystery is solved.

Follow up: Today I had a conversation with the tech at Classic Auto Air (tampa) that repaired my power module. He told me how to calibrate the Transducer:

Remove power wire that goes from the transducer to the plug (detach at plug, NOT transducer). Start car. Attach vacuum gauge to outlet side of Transducer (the large hose that goes to the power module vacuum chamber), which should be putting out full vacuum in that condition. Note that there's a small screw on the bottom of the transducer which you turn until you just barely see that the vacuum reading on the gauge is just barely starting to drop-then you go back on the screw just a smidge and its done.   

I will be trying it in the next day or so.

The Power Module and the insulation repair DID return proper functionality to the system. Tony; I get hot air from the heat outlets and cool air from the AC outlets. The only thing left to do is to calibrate the Transducer with the Temp wheel, and that's relatively simple. I do agree, it makes the car more enjoyable!

Glad you got to the bottom of the blockage issue
Should be on your way to getting your AC and heat up and running
That will be a very nice thing to add to the comfort of using that great car

Enjoy

Brighter Headlights. What to install that won't draw too much current.

Posted by Norman Silverman on December 15, 2018 at 9:07pm 7 Comments

My car still has its "T-3"headlamps and they shed poor, yellow-tinted light. I'd like to replace them with something that most folks on this web site use, that would shed good light and don't heat up the wiring with too many amps. 

Survey says?

I recently took my car to a “Cadillac” “Specialist here in Los angles CA.

After leaving my car to diagnose my steering column for not shifting properly. I get this txt from the shop owner. Mind you I just got the car and wanted to at least shift from the column without having to shift for the engine bay. Also wanted to get a price on dash lights to work. Basically I’m trying to feel out if he’s putting gravy on the labor.

Although the radiator was not leaking, nor was the car running hot, I tool out the radiator today to have it boiled out and rodded out. Then I changed the oil and filter (filter is very easy to reach with the radiator out), then the thermostat got changed. 

I'll have the radiator back from the shop on Monday, and will reinstall it then. 

Still having…
