Heater motor is prone to water damage when the small drain scuttle drain gets blocked (usually by leaves).
If the passenger footwell carpet is damp, that's probably the problem.
Worth checking regularly anyway, and/or remove the small cover over the drain which is part of the problem.
Remove the heater assembly (located over passenger footwell) and replace is the easy answer.
It is possible, depending on ability, to strip and repair.
New from Europarts around £130, used around £60.

Yes, in high it bypasses the resistor and uses a high blower relay. But I think on 1998 Astro the High relay and the resistor are built together. It should be mounted in the blower box real close to the blower motor.

I had the same problem on my 2004 Corrolla and ultimately it only worked on high. The dealer charged me $45 diagnostic fee and almost immediately told me it was a part called the blower resister. They knew the answer right there and then but only realesed it when I agreed to pay the diagnostic. They charged me 179.00 to fix the AC and later I found out the part cost $8.95 and a novice could have replaced it themselves.
