Heating issue not working at all

(1999 Mercury Cougar)
Hello I have had heat on 4 and it worked like that for over a year..Well I got in and now i have no heat at all So i bought a heat resitor well that didnt work..Had my blower motor checked and it was fine..Now trying to find where is the switch is located at any ideas? I did check the fuses...and relays..I got to work late tonight and its getting to cold for no heat.. Also there seems to be no power going to the heat resisitor... Please help this Girl out!! The power goes to the heat control switch but then there is no power going out to the resistor.

Did you inspect the wiring connector at the resistor very carefully? The "high speed" only fan for a while and now it doesn't work is a classic symptom of a failed resistor and melted wiring connector/terminals. You may have damaged terminals in that connector. Look there first.

I'm sorry that things aren't simpler for your car. The system, however, is fairly simple. It includes on the components we've talked about...switch, resistor, blower motor, wiring, fuse. All of it cannot be fine... If you have a good resistor and the wiring has no resistance, and the blower motor is good, then it must be the switch. You may need to get some more first hand assistance...I wish you luck and warmth!
