AC dash switches + ancient computers thread

Can any of you Eldorado short bus owners tell me how you turn on your air conditioning compressor? Do you use the Ford dash rotary switch or use a switch on the add-on panel that Eldorado installed on the motor cover?

I'm just about to re-work my engine mounted air conditioning and I want to have the wiring right before taking it in to be recharged. Naturally, I can't try turning on the compressor until the system is pressurized.

Re: Aerotech AC dash switches

Well, I started out tracing a few wires and ended up dismantling almost the entire HVAC system in the Ford E-450 engine compartment. The mechanical stuff was easy enough but the control circuits sure had me talking to myself. I now have a pretty good understanding of the E-van HVAC system. Working on a bus conversion is nothing if not a learning experience.

To answer my own question, the front blower fan and AC compressor are, in fact, controlled by the dash switches - at least on the Aerotechs. In my explorations I found one bad dash switch, a blower fan on it's last legs and a broken fan resistor so it wasn't a total waste of time.

I also rebuilt the van air conditioning and removed 60 feet of AC hose (while cleverly absorbing quite a lot of compressor oil with my T-shirt ). Not bad for someone who didn't know diddly about auto air conditioning three weeks ago.

Re: Aerotech AC dash switches

Another thing I learned:

Don't use penetrating oil in plastic parts. The resistor connector was being stubborn so I sprayed on some PB Blaster and waited 10 minutes. The connector came out all right, but in little pieces.

Re: Aerotech AC dash switches

This may date me, but when I first started using computers there weren't pictures of any kind, it was all green screen text. No Internet either. Later my online experience was Compuserve or AOL at $12.50 an hour. Playing Zork was a major thrill! If you wanted porn you had to fire up your imagination.

We live in a different world now.

Re: Aerotech AC dash switches

It's been a while for me as well.... I started with a 600 Baud modem connecting to BBS both local and not so local.... Man I remember when DOOM first came out and you could play over the phone lines with friends...... Yelling "PUT DOWN THE PHONE, I'm ONLINE!!!!" and then being dead...lmao those were great!!

This happens a lot here

Atleast people don't run to moderator police

Kinda on track,was the switch just brittle like dried out UV plastic or did it actually look like a gummi bear left on the dash?

Re: AC dash switches + ancient computers thread

It looked like white plastic but I will say that the plastic receptacle it plugged into didn't fall apart when I sprayed it. Who knows what it was actually made of. Didn't melt so much as just crumble when I tried to pull it out.
