1999 S10, it should be under the hood, on the firewall, on the passengers side, close to the blower motor.
There could be two separate problems. Check the blower motor resister, and the ABS sensors for problems that could cause this.
Only for the high speed blower function. The lower speeds go thru the blower motor speed resister.
The blower motor speed resister is burned out.
First, take a socket wrench to remove the cover of the blower motor of a 1993 Chevy truck. Then pull the motor blower out and install a new one in its place. Lastly, screw the bolts of the blower motor cover back in.
In the truck!
Check the blower motors ground and power in the truck and the blower motors resister......
The fusebox which controls the blower motor is under the hood up by the firewall.
The blower resistor on a 1999 Chevy truck Z1500 is located behind the glove compartment. There is also a resistor on the firewall next to the blower motor itself.
You will have to replace it. The bearings are worn out in the blower motor.
The blower motor can be replaced on a 1995 Chevy truck by first disconnecting the battery. It helps to take a picture of the blower motor before dismantling, so that it can be put back easily. Disconnect all the wires from the motor, then remove the bolts holding it to the firewall. Replace with the new motor and bolt it in, then connect the wires. Reconnect the battery.
You gotta start by figuring out what's wrong with it. You need to determine if it's the blower motor itself, or the power supply, then troubleshoot to determine the exact cause.
Connections get corroded and loose, causing resistance which causes the wires to heat up and melt.
behind the glove compartment, to the left
The blower motor resistor pack is defective. Replace it.
About 15 mins. That's a easy job.
double check that it's the motor most times it's the resister for the fan speed In the firewall on the passenger side of the truck is the blower motor speed resister coils, they burn out alot. I could not find one for my Dakota so I got one from a dodge caravan and I changed the wirring, that is the most likely problem
Swap the relay with a known good one, many of the relays are of the same part number. Keep in mind that the blower motor relay only controls the high speed function. The blower motor speed resistor and the blower motor switch controls the lower speeds.
Could be,The blower speed switch or electrical plug at switch is burned out. The high speed blower relay is burned out. The blower motor is on its way out. The blower motor speed control resister is burned out, The cabin filter (if applicable) is very dirty.
Remove the wiring harness from the back of the blower motor. Remove the blower motor retaining screws. Remove the fan from the blower motor. Reverse the process to install the new blower motor.
There seems to be a problem with your 2002 Chevy 1500 truck. I think you may need to check out the left water tank as the acidity may be PH9. Hope this helps
You may have a vacuum leak
Its should be behind the glove box.. held in by 1 screw
Your truck has both. the resistor is between the switch & blower.thje resistor controls the blower speed
The 1997 Dodge ram blower motor is located on the firewall in the engine compartment. The blower motor will be near the bottom, passenger side, firewall.
