the switch is on the dryer, and if it is low on freon it will shut it down. You really need to let freon into the system and see if it will kick in. Then your gauge will start working.
The switch can be on the dryer, but also on the line CLOSE to the Dryer. It will be up front at the evaporator area. You just jump both wires to get the compressor to come on. Now, you can add 134a, but the odds are it will be gone in less than a few days. You have a leak somewhere and probably NOT a small leak. But there is no harm in adding a few cans of 134a to determine how long the system will run before it leaks out again. IF you have both the HI and Low fill hoses connected, by opening the HI line to the 134a can, that will trip the low pressure switch to come on momentarily and you just keep opening and losing the HI side valve until it gets enough 134a to keep the switch closed to then fill the system full. Do you have an idea of howe much 134a to install? I always like to ask this question. 4 lbs is a full charge on a Roadmaster chassis with the Evanstempcon system. Doug
