I never worked on a Delorean with the switch on the left side, only seeing it. It would make sense that it is only a high pressure cut-off as that is all that is on that side of the condenser coil. My point in bringing up about the switch on the left side is that it too could cause short cycling but in it's case cycling on HIGH pressure which is caused by too much freon or air in the system or the electic cooling fans not working. I don't think that it is adjustable but I don't know not having actually worked on a car with it. Again the only way to properly work on the A/C system is to have a gauge set hooked up so you can observe the system pressures and then know what is going on inside. BTW when converting to a different freon the high pressure switch may no longer be calibrated properly, most substitutes condense at higher pressures than R-12 so that may be the cause of the short cycling. Another reason to try to stay with R-12 or a drop-in replacement. David Teitelbaum vin 10757 --- In dmcnews@xxxx, "Marc A. Levy" <malevy@xxxx> wrote: > Are you sure about this? The switch on the condenser coil I believe to be a HIGH pressure switch (only on the later cars). The low pressure switch is always in the dryer canister. > >
