1992 Olds Toronado dash lights and heater fan out

My son has a 1992 Olds Toronado Trofeo, and his dash lights are out. The park break light and engine lights come on but that is it. I replaced all the bulbs and checked the fuses (just looked at them) didn't put a meter to them. Some people are telling me he may need a twilight sentinel switch (not mechanics) . Also I noticed his heater fan is not going on (it was working previously but it would be turned on then later come on) now it is not coming on at all . Are any of these related to one sensor or item..please help--thanks alot.

SOURCE: location of the temperature sending unit on a 1991 olds toronado

Ok, you have three sensors on this engine that work together to manage the temperature reading that are sent to the gauge. i recommend checking all three to be safe. i will list the sensors and, locations below.

1. Coolant temperature sensor- Under hood, driver side, upper engine area, above transmission bell housing, mounted in driver side end of intake manifold.

2. Engine Temperature sensor- Under hood, driver side, upper engine area, mounted on rear cylinder head

3. Temperature switch.- Under hood, center, lower engine area, above oil filter, rear of coolant temperature sensor, mounted in engine block

SOURCE: Electronic dash goes of and on on 1988 Oldsmobile Toronado Trofeo

A short is likely to blow a fuse or burn something. Most likely you have a loose or cracked printed circuit board behind the dash. If you can get the panel out intact, turn the key on, bend and push/pull various areas in the board while watching the display. You won't get shocked by doing this, but if the printed wiring touches any body metal, it can damage the printed wiring permanently. Check around any socket areas particularly. Good luck!!

Thermostat replacement.

Drain the coolant into a suitable container. Follow the upper radiator hose to where it connects to the intake manifold. Loosen the clamp and disconnect the hose. Remove the coolant outlet retaining clamp bolt, then the clamp, then the outlet. It is pressed in with a large o-ring to seal it. The thermostat is under the outlet. If the outlet is corroded, replace it as well. Use a new o-ring, and lubricate it with dielectric grease before reassembling. Check your connections and refill the cooling system. Be sure to purge the air from the cooling system after refilling.

Sounds like a bad heater element switch or heater core. Sound like the heater control switch. On the front side of the heater core you should find a plug. Pull the plug and remove the two screw. The switch should come out. Replace it.
