heater/AC fan not working

[mdhbhouse]

I have an old 91 Plymouth Voyager and starting today the heater stopped working. I mean you try to turn it on and nothing, no blowing of anykind (hot or cold). The rear heater still works and I can control it from the front as always.
Is this a fuse problem or more of an electrical problem. Everything else seems to still work. I've visually checked the fuses but I don't actually see anything labeled as heater or fan.
I'll double check fuses for something blown but wanted to start with a post.

I've seen a number of posts about no heat (thermostat related etc.) but this is not my problem. Just doesn't trun on!

TIA, Mark

Update:
Checked and replaced 30A fuse in slot 26 label'd A/C-HTR fan.
No change

Another possibility to check: It could be a blown relay that supplies the power.

Strangely enough it is working again today after being parked in the garage overnight? Last night I started surfing around and found some hints on heater blower replacements and a blower motor resistor failures

Let's say is was a relay. Those are under the hood in a line with other realys's right (never claimed to be a mechanic )?

Right now I guess I'm in a wait and see situation although I plan on investigating how I would find the heater motor resistor and how you'd test a heater blower motor.
