could be a fuse, a relay, the blower motor or the blower resistor.
It's easy to check the fuse, using the owners manual.
I am not sure where the relay is, and it requires special tools or replacement with a known good relay to test.
If the blower works on high and no other speed, then the resistor is bad.
If fuse and relay are good, and blower does not work in any position, suspect the blower motor itself.

1993 Pontiac grand am se heater goes off an on at odd times but. It does not work when you turn on it just comes on when it wants?
My suggestion is to look for a wire that has a break in the insulation. When it makes contact, the heater runs. Did the car also suffer from some blown fusesalso?
Why is your 91 Buick Skylark blowing out cold air even when driven for 30 miles?
Thermostat stuck open or heater core plugged. CONSIDER THE POSSIBILITY YOUR HEATER VALVE IS CLOSED/CABLE RENDERED INOPERATIVE BY A BROKEN PLASTIC SLIDER HOUSING,AS IS OFTEN THE CASE ON OTHER MODELS/MAKES,SHOULD IT NEVER WARM UP.

If a 1997 Jeep Grand Cherokee Ltd only blows hot air but the fan speed still works what could be wrong?
Well, I can't solve the problem but my '98 Grand Ltd has also begun blowing hot air only. It does it on any heater setting,hot or cold,and the a/c running makes no difference--still hot only.It is as if the system has locked up somehow. In an old manually operated heater it would be a fault with the hot water valve sticking and not closing off. From reading on this site it seems that it may be related to the air blend door sticking.Allowing hot air only---and costing around $850 to repair.There must be a better way !
