Re: What about my AC high pressure cut of switch?

["Jim Reeve" <ultra@xxxx>]

Michiel, after reading your post, I was inspired to go out to my car 
and take a picture of the AC Accumulator area. I did so, and 
labeled all of the components. I uploaded it to the "FILES" section 
of YahooGroups, under the name "AC_Accumulator.jpg". You may find 
the answers to your questions there. To answer them here, the high 
pressure switch is located on the metal line leading into the 
evaporator, in front of the accumulator. The safety valve is 
opposite of it (they rest horizontally). The low pressure switch is 
located on the top side of the accumulator. If my knowledge of AC 
systems is accurate, the Low Pressure switch is responsible for the 
normal cycling of the compressor, and the high pressure switch is 
only a safety. And for those who really dont know, the accumulator 
is located in the front passenger-side wheel well.

However there are two factors you must consider here. The ealier 
cars had a different setup at their accumulator. According to PJ 
Grady's online parts manual, the switch was at VIN 3467, which is 
after your VIN. My diagram of the later design off of my VIN 6960 
would not be accurate, and I dont know the setup used on the ealier 
cars. Another factor to consider, did the AC shop that did your 
conversion use DeLorean parts, or generic parts? If they used 
generic parts, the setup may also be different than I have pictured.

As to your other question about removing the lines, it can be done 
without lifting the body, but not easily. You will need to cut off 
the ends to the lines to pull them back, and it may also require 
bending down the ledge off of the bottom of the frame.

Good luck fixing your AC.

THEY? And if compressors should cycle on and off all the time, which 
component is controling this?
