My 94 del sol stopped blowing heat. I feel the warmth but when I turn the heat switch nothing happens. Do you guys think it is the switch or the blower motor? I checked all fuses already. The car only has 74,000 original miles so I'm leaning towards it's not the switch.

 

its just not blowing? check relay. do you have a tuck? check passenger side wires under hood.

 

There is a resistor pack in the fan that can go bad quick test turn the fan speed all the way to high if it runs the resistor pack went out. If no then check for power at the fan motor plug with a dmm if it there then the fan is bad. if no check the switch its not a common problem but they do go bad

 

Where is the fan located? By fan do you mean blower motor?

 

Yes blower motor it should be located behind the glove box
