Where are the resistors on a Chevy pickup?
Two individual resistors make up the blower motor resistor assembly on your Chevy pickup. As you’re probably already aware, these resistors are located between the A/C-Heater control panel and the blower motor. The purpose of these resistors is to reduce the amount of the blower motor’s current that’s passing through them.
What kind of blower resistor do GMC pickups use?
NOTE: This tutorial only applies to the 1988 to 1993 vehicles listed in the ‘Applies To:’ box on the right column. Some 1994 Chevy/GMC pickups use this type of blower resistor. For the 1995 and newer blower resistor test, the following tutorial will help:
Where is the blower resistor on a 1988 Chevy?
The blower motor resistor (located on top of the heater core housing and behind the glove box) isn’t hard to test. In this tutorial I’ll show you how to continuity test it with a multimeter in Ohms mode ( Ω ). NOTE: This tutorial only applies to the 1988 to 1993 vehicles listed in the ‘Applies To:’ box on the right column.
What happens when a blower resistor Assembly fails?
What usually happens when the blower resistor assembly fails is one of the resistor’s wires burns ‘open’. So, it’s a good idea to remove it and visually check that both resistors are not burned ‘open’. If any are, then there’s no need to do the continuity tests below since you’ve found the problem.

Where is the resistor on a blower heater?
The blower motor resistor (located on top of the heater core housing and behind the glove box) isn’t hard to test. In this tutorial I’ll show you how to continuity test it with a multimeter in Ohms mode ( Ω ).
How to replace the blower motor resistor on a Chevy Silverado?
In this video we show you how to replace the blower motor resistor in a Chevy Silverado, Also it is very important to consider the blower motor anytime a resistor fails. A worn out blower motor may still work, however it will require more amperage to operate, this extra amperage is pulled through the resistor and can easily burn it out. Loading…
How to test the blower motor resistor ( 1988-1993 pickup )?
CASE 2: All circuits tested had continuity where indicated in the test steps. This is good and is the correct and expected test result that tells you that the blower motor resistor is OK and not the cause of the blower motor speed problem. If your pickup’s blower motor resistor passed this continuity test, you can stop here.
