Question about 2002 Chevrolet S-10
I have replaced the resister and the relay, with doing that the fan worked like it should for a day or 2. Now the blower does not work at all. I by passed the wiring for the blower and that made the blower work on high. So I know the fan works what could be the problem?
Should be the switch on the dash has bit the dust. The way it works sometimes is the blower motor is only one speed (high) and the switch on the dash has a resistor in it to accomplish the different speeds. Add another switch off most any car or truck to the hot wire you already installed and see if that doesn't fix it. You should need to be sure the substitute switch has a grounding wire capability.

SOURCE: blower fan only works on high
If it is working at all then the relay and fuse is good and the problem is either the little vacuum hose on the back of the control switch panel or the panel itself.

SOURCE: Blower motor or resistor?
Yes its the blower motor resistor.
More then likley theres some trash or something in it, or possibly the motor itself is on it's way out. There not that bad to pull out of that body car, just pull it out and see what you can see.
The blower motor is under the glove compartment
You can replace the resistor on your own. Please find a detailed diagram which would guide you to do it.

It probably is the fan switch itself. They are around $30. for a new one. You can take it out and check to see if you have power to all the settings with a ohm meter or test light. They are not real hard to take out.
