Comfortron AC trouble shooting

[Norman Silverman]

OK, here we go.....

I got the book to troubleshoot the system. INDISPENSABLE to this effort. 

As I do a cursory exam, I see that the AC RECIRC SOLENOID is Cracked (the WHITE one in the engine compartment coming out of the HVAC body with two vacuum hoses on it). I tried to patch it up (cracked all around the base), but it does not look like it will hold. 

PLEASE TELL ME THAT REPLACING THIS PART IS NOT AS DIFFICULT AS I THINK IT IS, But I think it is a bear to do....

Since a good deal of work is done under the dash, is it just easier to remove the dash top to be able to access everything more easily?

Comfort control repair -- will pull up a lot of info on the subject and Clovis's thread

A good deal of work is done under the dash in very strange poitions that use muscles you forgot you had -- but real nice having that system up and running --to help maximise the enjoyment of your exotic Claasic Antique Cadillac
Removing the front seat and pushing it back does help me get in there

I have aquired all the parts and will be pulling my entire system out replacing all parts required over the next two - three months
A big project for me at my age but looking forward to having the system working correctly

Clovis - Thanks for posting and sharing your comfort control info with the group
You have inspired me to -- Jump Right in - and Get Her Done ! ( Soon )

Thanks. I'll look for Clovis' writings. At this age I can spend more easily than I can bend, so if I have to be a contortionist to do this repair, I'll look for a pro. I have the book on Comfortron and it is pretty complete and simple to follow.

Mostly that part needs to hold vacuum ( a vacuum valve )
The biggest problem is once you get into the comfort control system in most cases you will need to be spending 800-1000 dollars --on parts to be replaced --doing the job yourself -with some understanding what must be done first and the skills to get that done
Yes --bringing this system back to life with very old parts to make it reliable again will take some doing for the mechanically inclined among us

A genteman named --Clovis --has written a thread on this site that is extremely helpful in getting an understanding of what must be done the costs involved ( where to located the parts needed ) and may give you the encouragement you just need to attack the task
