Question about 1993 Geo Storm
My 93 Geo Storm (1.6L, auto) started lighting up the 'battery' and 'brake' lights on the dashboard. When that happens - 1) the dashboard lights get brighter, 2) the a/c compressor seems to cut off, 3) the fan motor (a/c,heat) shuts off. We just replaced the alternator and the 1st 10 miles were fine, then the a/c compressor stopped, and both lights came on again (battery & brake). It seems something is making the alternator overcharge. Now, both the radiator fans (2) and the heater, a/c fan do not work. No blown fuses. very odd. I am trying to find a wiring diagram to check the relays, etc. Any ideas?
Engine was running too hot, thermostat s/b 180, it was 195, antifreeze solution had too much water, this caused the radiator thermal switch to trip. I think the alternator was either bad, or the excessive heat made it draw too much. Two separate problems.

this warning light or any other stays on in the dash it is indicating
that the systems control module (or the system sensor in the case of
lights like low oil pressure, door open indicators etc.) has detected
a fault, it then disables the system (this applies to ABS,TCS, TCM,
SRS and BCM faults and others) as long as the light is on. You must
now have the dealer hook up a special electronic diagnostic tool and
"scan" the system for the fault code that is stored for the
Legend of Abbreviations. ABS Antilock brake system.TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module
