Why does my heater control lights flash on an off on my 1990 Z71
Because it is hot and the heat is making the metal spark.
This is for the Heater/Fan/Cooler lights. To replace the bulbs remove the control knobs by pulling them off, the front panel can be pulled off using a small screwdriver, pry it off on the right side then remove the clear diffuser panel and twist and pull the small bulbs out. There are 2 bulbs for that heater knob control. (bulb # 90069-98004)
The heater control valve is used to shut off hot coolant from entering the core when the heater is in the off position. A heater control valve can be actuated by either a vacuum line or a cable from the vacuum heater control valve to the heater core. This hose should be warm; if not the heater control valve is stuck and needs to be replaced
take off your dash bezel that stretches from your gages past your radio then remove the heater control box and it will be on the back twist it out and replace your bulb for around $1.00.
To turn off a baseboard heater, locate the thermostat or control knob on the unit and set it to the "off" position. This will stop the heater from generating heat.
Remove the radio/heater control module. Disconnect the temperature control cable at the base of the control assembly . It is on the center mound just to the right of the gas pedal. Take the heater control cable off of the back of the heater control module. Pull the temperature control cable off.
replace ur BCM (body control module)... mine did the same thing
probably your altenator or batterys power is focused on one point of output
The BCM (Body Control Module) of the Passlock system is malfunctioning. It will need to be replaced. I just had it done to my '03 Impala.
If you mean you have amber fog lights, and you want them to work as turn signals whether they are switched on or off, I'd use an XOR circuit... A=Fog switch B=Flash signal AB Fog 00 Off 01 On 10 On 11 Off aka XOR -Matt
To control remote control can lights in your home, you can use a compatible remote control device that is specifically designed for the lights. Simply point the remote at the lights and press the appropriate buttons to turn them on or off, adjust the brightness, or change the color if they are color-changing lights. Make sure the remote control and the lights are within range for proper functionality.
This sounds like an issue with a fuse. In newer sunfires, if the Radio/ACC fuse blows, no indoor lights work and nothing will turn itself off when the car is off (meaning your daytime lights will stay on even with no key in the ignition). It's a 20w minifuse, walmart sells a pack for about $3.50.
