The vacuum tubes behind the panel might have broken or become disconnected. This system operates the door that controls defrost to vent routing of air in the car's ventilation system.

Hope this helps.

I have replaced the blower relay, the resistor looks fine, but blower won't work on my 1986 Silverado

Change the resistor. For the 15-20 bucks it's a great diagnostic and a very common problem with GM vehicles.
Then you can start backtracing the harness as ray012965 suggested.

You will need to replace the fan blower motor switch resistor as well as the blower motor resistor harness.

The resistor can be located under the glove box (directly above where you passengers right foot wood be pointing if sitting in truck.

This is a common problem much has been written about it. You can find a detealied fix on youtube.,

Fan motor blower not working

According to the wiring diagram, there are only three components to the system. The blower motor, the resistor, and the speed control switch.
The resistor gets power from the switch which is powered by a 25amp fuse. On high setting the resistor is bypassed and the blower motor gets power from a 30amp circuit breaker. The blower is grounded to the body. The fuse is hot in the "run" position and the 30amp breaker is hot all the time.
So you should have power at the blower motor on one of the settings and a direct ground on the black wire.

Fan speed only works on high which should have the least resitance. I can't find the relay that should be on the pass. side under dash. can someone direct me?

You likely need to replace the Resistor which controls the voltge delivered to the fan motor.
Your symptom shows this is right.

The resistor is inside the air box directly in the flow of air from the fan. You MUST have it fully installed before powering on the fan or it will burn out immediatly. Needs the air flow to keep cool.
You may need to pop out the glove box, then you should see a few wires going into the air assembly under the passenger side, being held in with 2 screws. Yours maybe slightly different. Ignition off, remove the couple screws and extract the plastic block holding the resistor lump. About 12 - 20 $ at auto parts store to replace. Pu the new one in and screwed down BEFORE turning on ignition.
Good luck

99 explorer fan only works on high

You need a blower motor resistor pack, follow the wire from the motor it will go into a connector with a few wires at the resistor pack. it's held in by 2 screws- easy to change.

My hearter fans will not turn off. when i turn my truck off.

Relay for the heater fan is the most likely problem, replace the relay and if that does not fix the issue the problem could also be in the resistor pack for the fan control.

MY HVAC fan stopped blowing. Checked all the

Check the blower motor speed control resistor pack is ok.
(The resistor pack is usually located in the blower fan ducting in the air flow).
Check condition of electrical connection terminals on the blower motor circuit - these terminals pass considerable current and over time may fatigue overheat and loosen.
Check operation/replace any blower motor control relay,
Check the blower motor will run if +12v directly applied to the blower motor.
Check operation of the blower motor speed control switch is ok.
