Comfortron

Postby Jodyamblard » Tue Feb 09, 2021 10:51 am

I have had some experience with the Toronado's Comfortron automatic climate control.

The first car I ever drove was a 1967 Toronado. I got to know and made minor repairs to its Comfortron system over the years.

I became the proud owner of a beautiful 1967 Toronado on August 7, 2020.

I had a chance to calibrate its Comfortron system, which works like a charm. And I possess a Comfortron tester model J 22265, which I would be pleased to lend to anyone who may need it (although you can diagnose most of the basics without it).

I would also gladly share my experience, and offer my thoughts to anyone working on the system.

That's pretty cool. Thanks for the offer. Your car is gorgeous.

My car just has the "normal" heater/blower system.

Thanks for your comment, Otto.
I love the colour of your Toronado.
It must make quite a hit wherever you go.

Best, Jody

It was the color that made me buy it. It's called Dubonnet.

I just noticed that your car has the correct thin stripe whitewalls. Are they from Diamondback?

Would LOVE your help on getting mine working. I cant seem to control it but it will turn on by itself without notice so know something is working :). Do these cars all have the same heater valve (regular and comforton) ? the prior owner just put in a manual stopcock valve on my car.

Hello Todd,

It's great news that it turns on by itself!
Once on, can you adjust the temperature and see if the blower speed or temp changes? You seem to have indicated that you can't control it.

Nevertheless, once it's on, does it JUST blow hot? (you may have to wait for the water to reach operating temp to feel the heat).
If so, not so bad. My next step would be to have to look at the transducer on the floor under the glove compartment.

Let me know before you check it, I have some advice. It's got a delicate wire filament inside the tube that you must be a little careful with.

In any case, when the outside temperature is cold and the comfortron calls for heat, the blower NEVER turns on until the water temperature reaches a certain temperature. So your car may just be normal.

If the comfortron is calling for cooling on a HOT day, I'm not certain if this would still be true (the blower waiting for water temperature). But I'll check this out as soon as I can. I have to wait for a hot day here in Toronto, but it shouldn't be long now.

I'm not sure whether the heater valves were different in different models, but IF this were the case, it wouldn't be hard for you to find the right one on Ebay . Keep in mind that it's a temperature SENSOR that initiates the comfortron's blower motor, not the heater valve (if I've got this right).

Do you have a repair manual for the car that covers comfortron for your year? Please let me know what year it is.

Hope this helps. Please keep me posted, Jody

Thanks! it is a 66. The compressor is toast, so sure it was not cool when it kicked on. When on I can change the blower speed low or high by the switch but will try with the temp control. I have never opened the heater valve yet so sure the heater core is not hot, the valve is closed.
I have never seen anything under the glove box, I just removed it so know there is nothing underneath. The 66 has a grill on the center top of the dash board so think that is the sensor.

Hello Todd,

Thanks for your note. 1966 - sounds nice, what color?

I'm glad the blower works on both Hi and Low. A good sign for sure. You might try defrost and De-ice too just to see if the dampers redirect the air to the windshield. By the way, De-Ice should blow at full heat regardless of the temp dial.

Let me know if after the car warms up if you can modulate the fan speed/temp with the temperature dial. I understand about the heater valve so you may not be able to feel hot air. But still let me know if you do or if you can hear the dampers redirecting the air . Try De-Ice to see if the air at the windshield blows hot after the car has warmed-up.

About the transducer: It resembles a tube as in the picture below: It would be on the passenger side affixed laterally on the upper part of the floor (screwed into the carpet) below the glove box. I'm pretty sure you should be able to find it by lying down on the floor. It's sometimes a source of problems, and I want to make sure you have one. See the picture or check out this link: http://www.toronado.org/forum/viewtopic.php?t=1499

The little grill on the dashboard is one of 3 or 4 temperature sensors for the cabin. Usually bullet-proof.

Please give me a call at (647) 787-4194, and we can talk about this a little more.

Best, Jody
