You're in CT? Can you attend NEBF? That'll be your best help at this point. But I'd GUESS right now the resistor pack for the fans is shorted. It'* not hard to get to, even if it sounds like it is.
Remove the maxifuse relay center cover and loosen the relay block, lift it up, and remove the small cover on above the heater core.
Step 1 in this Techinfo article describes access:
(good time to follow the rest of that article also).
Check your blower resistor pack with an ohmmeter.
You should have:
.16 ohms a to b
.70 ohms a to c
3.07 ohms a to d
2.37 ohms c to d
2.91 ohms b to d
The circuit looks like this:
If it doesn't shoot out like that, replace the module. My bet is that it'* bad. There is no harm other than annoyance right now.
Your local parts store should have or be able to get one for under 20 bucks if you need it. Rock Auto has it for your car for $11.75 if you need it. Make sure you don't get the MODULE for the cars with Electronic Climate Controls. That'* about 100 bucks.
