I have a 92 Bonneville SSEI. The temperature flashes when started. Compressor does not come on. Econ shows on display except when in defrost (but compressor still off). I checked fuses (driver, passenger, under hood). I have voltage at the AC fuse under the hood, but there is no voltage at the connector to the pressure switch. Any ideas on the most likely causes/cures? In the past the temperature would flash, but the A/C would work. Car has 200k+ miles on it. Was blowing cold before compressor wouldn't come on.
