Question about Cars & Trucks
WHEN I TRY TO TURN ON THE AC OR HEATER, THERE IS NO AIR COMING OUT, THE DISPLAY SCREEN SHOWS THE BARS FROM 1 TO 8 INCREASING AS I TURN THE CONTROL KNOB, THE STICK FIGURE SHOWS THE DIFFERENT LEVELS OF WHERE I WANT THE AIR TO GO, THE AC GREEN LIGHT ILLUMINATES WHEN I PRESS THE KNOB. A MONHT AGO THE AIR WAS STILL WORKING, BUT ALLL THE SUDDEN THE AIR WOULD STAY ON FULL BLAST NO MATTER WHAT SPEED I CHOSE, THEN IT JUST SHUT OFF AND HASNOT WORKED SINCE. A MECHANIC FRIEND OF MINE SAID THAT IT WAS PROBABLY THE BLOWER MOTOR CONTROLLER. CAN SOMEONE HELP ME?
You can have your mechanic friend test the motor under the hood where the wires plug into the blower. It sounds like the motor has went bad in my opinion, but it could be the plug is loose. I will be hoping its just loose for your sake and good luck!

SOURCE: Heater Fan does not work
Sounds like the fan control knob has shorted out. You can check the fan "blower" relay and fuse in the engine compartment but you need to make sure the control knob is good or you will keep blowing fuses and relays. If your blower fuse and relay are good, then just have the control knob checked and replaced if needed.

I'm assuming the problem is the blower motor isn't coming on or working. 1st, check the fuse. 2nd, remove the glove box or pull the 2 tabs that act like stops when it's open ( the glove box will open out further) and you'll see the power plug connector for the blower unit. Turn on the blower through the climate control (heat, A/C, or whatever) and wiggle the connector to see if the blower turns on. If starts working, then an easy solution is pull the connector off and gently press the prongs together or inward. Then carefully reconnect with damaging the prongs. This worked for 96 Mark VIII due to the fact the prongs were not "seating" correctly in the female connector. It's been about 2 years since I did this and the connection is still good. If wiggling the plug doesn't work, pull the plug, turn on the climate control (heat, A/C), and check for voltage to the plug. That's about all I can help with.

This is definitely 100% the Blower Motor Resistor.
Replace this and all speeds will work fine.
This Resistor is defined with 3 to 4 wires going into it, and is located adjacent to the Blower Motor.
It is easily access, removed and replaced.
I will post an additional comment on Part Number, Price and where available.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!
