Low speed on heater fan does not work. All other

You will need to inspect and test the speed control resister and the speed control knob first. What have you done so far?

Heater controls

It may be your blower motor RESISTOR, in gm cars it may look like a card that is connected near the blower motor,under the dash, on most cars this is what gives you variable speeds, except on the HIGH speed is usually wired directly to the battery through a relay.

Heater control fan only works on speed 5. Removed heater control, what does the resistor look like? I'm asuming it's not a regular electronic resistor right?

Your looking for the blower resistor. Its on the passenger side under the dash. Two of the wires go the the blower motor. The wire connector and the resistor can burn or corrode. The replacement is easy two screws hold the resistor in and the connector can be replace with **** connectors.

My heater only works when i go above 50 miles an hour, and it only blows one speed, what is wrong?

Having to increase speed to get any heat means that your coolant may be low, as far as only 1 speed, the switch for the heater may not be working properly

In my truck, the fan only works on number 4, what could be wrong and could i fix it myself?

Could be the resistor. It may be either under the dash or under the hood. You can buy one and put it in but check all the fuses first. The resistor is a thing that goes into the heater box . It controls the fan speeds. The highest speed is usually handled by a relay. The resistor has these coil spring like things on the backside and they can burn out. You won't see them until you remove it. It will have a plug in with fairly heavy wires, maybe 5 or 6 wires

No heat , fan runs on speeds 3,4and 5 not on 1 or2

coolant flows thru heater core all the time temp is controlled by have a blockage in core,try removing hoses and backflushing heater core probably a little bit of scale stopping inlet.the fan speed is probably the blower resistor it is locateed next to blower motor under dash check the plug they burn up
