On a 1980 Trans Am, the choke heater control relay is typically located in the engine compartment, mounted on or near the firewall. It may also be found near the battery or on the inner fender. To locate it, look for a small rectangular relay with wiring harnesses connected to it. Always consult the vehicle's service manual for precise details and diagrams for your specific model.
the purpose of the choke relay is to supply power to the choke heater ONLY when the engine is running; otherwise if you left the key in the run position but the engine wasn't running the choke would open up even though the engine wasn't warmed up. then when you tried to start it, it wouldn't start because no choke. the control circuit for the relay usually comes off of the back of the alternator triad winding (alternator not turning=engine not running). without looking at a wiring diagram i can't tell you the details of the wiring but that's the idea of it- engine running turns relay on and sends power to choke heater and slowly opens up choke; key on but engine not running means relay is off and no power to choke heater. if the relay is not working, then no power will go to choke heater and the choke will stay on too long (or if ambient temps. are low it may stay on all the time). fast idle will stay on also as it is hooked up to choke linkage.

Yes, the 1993 Mercury Topaz is equipped with a blower motor relay that controls the operation of the air conditioner and heater.

On a VW Golf MK4, the heater control relay is typically located in the fuse box, which is found under the dashboard on the driver's side. You may need to remove the cover of the fuse box to access the relays. The specific relay for the heater is often labeled, so referring to the diagram on the fuse box cover can help identify it. Always consult the vehicle's manual for precise location and specifications.
The relay switch itself does not directly spark the fuses for the radio and heater; rather, it acts as a control mechanism that allows current to flow to these components when activated. If either the radio or heater is drawing too much current, it could potentially blow a fuse, but this is a separate issue from the relay switch's function. Proper functioning of the relay ensures that the components receive power without causing a short circuit or overload. Always check the relay and fuses if there are issues with the radio or heater operation.
remove the glove box and there are three relays one is for the control door
