My 1992 Buick Park Avenue air conditioner is stuck in economode. It
was low on freon and when I put some in, the low pressure switch made
but the compressor will not turn on and the "Economode" switch is lit
like its keeping the compressor from coming on.
Any Ideas before I hot wire the compressor through the low pressure
Most systems cycle on the low pressure switch I think . The low
pressure side varies to much with outdoor temp to allow it to operate
like a home ac unit. But the switch on the accumulator is closed. This
system may have a lose of charge switch that I don't know about.
Do I have to reset something after recharge?
Started with one pound, however, Problem is now fixed. Found that the
system does indeed have to be reset by disconnecting the battery.
Compressor now runs and I can finish charging. The computer locks out
the compressor if the low pressure switch stays open or the system
sees high superheat. (low charge).
