Something must not have went back together correctly when replacing the heater core. Looks like someone has to do the job over again.

I took my car in for repairs including a new fuse. they replaced the fuse 5 times and it kept blowing. how long can you drive the car without one til it catches on fire?

You need to stop replacing the fuse and find out why it is blowing. It is blowing because you either have a short in the wiring, too small of a fuse, or the circuit is overloaded. If you remove the fuse then there is no danger of it catching on fire. Just make sure you do not install a larger fuse than is recommended.

The heater fuse for a 1993 Geo Tracker is located in the fuse box that is inside the engine compartment on top of the battery. It would also be a good idea to check the wires on the heater relay that is on the passenger side of the engine compartment on the fender wall. It is just behind the washer fluid receptacle.
