How do you know if your blower resistor is bad?

Unlikely a blower motor resistor problem. If the resistor is faulty. the fan speeds will not work/fail on the lower speeds. High speed will normally always work. If the fan is non operational suspect a fan motor issue.Bad fan motor/switch/wiring to it

2001 GMC Sierra 1500 fan is only working on 4 & 5 & the heater control is working intermittently.

The resistor is probably right next to the blower. Recommend you access the blend door to see why it is binding. There are procedures at the link below.

Heater / air conditioner fan control doesn't engage fan. Previously, it only worked in high speed.

I would replace the blower motor resistor first then see if that corrects this. The resistor is located next to the blower motor under the dash.

Heat and aircondition.My heat and air only work on number 5

Sounds like a "fan motor speed controller" or FMSC.
Either that module has gone out...or we're not getting the signal from the control panel sometimes called the EATC.

Lincoln has an EATC (for electronic air temp control)...GMC has something similar.
There is a way to run a diagnostic test of the EATC but am having trouble finding it for GM models.

If EATC test is done and will tell you it failed and would need replacing.
If EATC will tell you it passed and the fan motor speed controller would be at fault.

Usually, when a speed controller fails, the blower motor either doesn't turn OR it runs full blast.
Both parts EATC and the FMSC are expensive.
Since yours is running full least its providing air.
I'd try to run a diagnostic check to be for sure and maybe your parts might be less expensive and available at your local parts store.

Hope this helps...

What causes the fan to continue to run when controls are off?

This device is disclosed which causes a fan of a heating and/or air conditioning system to continue to run until the temperature in the duct work of the system reaches a desired temperature, so as to remove all heated and/or cooled air from the system, however, the device is designed so as to not cause the fan to be actuated due to changes in the duct work temperature which are due to changes in outside temperature or causes other than the operation of the system. A sensor which is located in the duct work controls the operation of the fan in response to temperature changes only if the sensor control circuit is first energized by the operation of the system.

Hope help with this (remember rated this help).

Blower/Switch Problem with Air Flow?

The extra air flow most likely turns the fan motor, check the fuses, check the fan motor switch for power if O.K. check the fan motor for power..
