Weird AC/HEAT problem, now inop...any ideas?

So this morning when I tried to turn the heat on, imagine my surprise when I heard no fan running. No heat, no air, no nothing. I feel like the resistance in the vent selection knob on the far right is a lot less than it was when it was working too. I have searched the forum and found nothing similar to this issue. Help me Tacoma fam!

No heat/ac
No fan blowing
RPM's do increase by 500 or so when a/c switch is turned on, but no action inside cab.

Please tell me this isn't going to be a 1000.00 bill! Thanks in advance for any ideas guys!

 

It's not going to be 1000 bill.

 

Not sure if this is your issue but I had stumbled across this article. It might help

to change the resistor would be a easy place to start.

 

I got kind of excited when I saw the "no air blowing" section of the article....but you had to hear your fans blowing in order for that diagnosis to work, mine don't. A good article though, thanks for the reply. I have yet to see anyone else with this problem
