Terrible timing for heater issue

I turn the heat on and it just kind of seeps through the vents lol. The blower motor is not turning on. Has this happened to anyone? Is it just a bad motor? Any ideas? Thanks guys.

if its what I'm thinking there is a little switch that controls the fan speed - it has a series of resistors (also called a blower motor resisitor) on it and it sounds like the switch has failed. This is in the top of the blower area under the glove box - might be worth checking this before thinking the motor has gone. Check FSM 21-6 and 21-8

Blower motor resistor only Controls the lowest speeds.
If you hit the blower motor to top speed it bypasses the resistor and should work.
So then you can figure out if the resistor is broken.

does not matter what setting the fan is on. does the same thing, sounds like im going to have to dig into the glove box. will i be needing to go behind the van controls themselves as well?

Check the resistor behind the glove box. It is black and screwed in with two phillips screws. Make sure all the coil springs are intact. It's uncommon for them all to go out at once though. Your blower motor may be shot. It's fairly easy to remove on a non a/c car.
