So I woke up this morning (raining out) to my climate control not blowing anything.

Any function I put it in it doesn't want to blow, if I put it on heat defroster the heat will come out but won't BLOW out. This is pretty dangerous as I can't see too well.

What could it be? A fuse? I'm thinking since its raining out maybe a short somewhere?

Any answers would help

 

The blower motor uses a 15 amp fuse in the interior fuse box located on the second row from the bottom far right and labeled "cooling fan."

 

Problem somehow solved itself? I'm guessing it was a ground.... It stopped raining.

 

In the pic provided shows where two of the three grounds related to the heater/Aircon circuit are located (third ground is located inside the car). Removing the plastic plug and then removing the metal block from the fender and cleaning up the metal part in addition to adding dielectric grease to the end of the plastic plug which connects to the metal mounting piece will go a long way in solving your problem in addition to the other problems which might arise if this particular group of ground wires become ineffective.

 

I had this SAME thing happen to me yesterday!

I just got done swapping the dash and replacing all the foam seals for the HVAC unit. It started raining on the interstate so I went to throw on the defroster and nothing... I could see the switching motor moving when i change the vent locations but no blower motor action.

I thought I forgot a plug or something so I unbolted the logicon and still nothing, yet after I bolted it back up it worked just fine....

Also, the heat no longer works, I can select it, and it will blow, but it does not blow hot or even warm
