Chassis A/C
Thanks Randy, I'll try that in the morning. I could use a
lesson on the theory of operation. You mention the low pressure switch. Without getting into the heat pump stuff of compressing gas and letting it expand at a lower pressure and consequently creating a cooling effect, which I basically understand, what's in the control path that makes this system work? What does the low pressure switch do? Are there other sensors/switches? AFAIK, the system does not use a thermostat; ie, it's either on or off. I guess she compresses until the low pressure switch turns her off and then when low pressure is hit again, the compressor engages. There may be some hysteresis in here too. So when I press the blue a/c switch on the dash, what does that do? Thanks, David Brady '02 LXi, Smokey, Va randydupree2000 wrote: >---ok,so now get a test light and check to see if you have power to >the low pressure switch,if so,and the power is not going through the >switch you have either a bad switch,or no freon in the system. >randy In WanderlodgeForum@yahoogroups.com, David Brady >wrote: > > -- No virus found in this outgoing message.
