Help get your fan speeds back with the Standard Ignition HVAC Blower Motor Resistor RU-769 — a 1993-1995 Chevrolet Astro blower motor resistor that also drops into the front HVAC position on the 1993-1995 GMC Safari (see the Buyer's Guide tab for full engine coverage). This resistor sets the resistance in the blower motor circuit that steps the fan through its lower speeds; when it fails, you may lose one or more speeds while high often still works.
If a failed resistor is why your blower only runs on certain settings, this replaces it.

This part cross-references / interchanges with the following part numbers:
What does the RU-769 blower motor resistor do?
It provides the resistance in the blower circuit that steps the fan through its lower speeds, giving you variable A/C and heater blower control.
Will this blower motor resistor fit my 1993-1995 Chevrolet Astro or 1993-1995 GMC Safari?
It fits the front HVAC position on the 1993-1995 Chevrolet Astro and 1993-1995 GMC Safari. See the Buyer's Guide tab for full engine coverage.
Why does my blower only work on high speed?
That can be a sign the resistor may be failing, since the lower speeds pass through it while high often bypasses it. Diagnose the cause before replacing.
Where is this resistor located?
It mounts in the front HVAC system's blower motor circuit. Refer to your vehicle service information for the exact access point.
What numbers does the RU-769 cross-reference?
It interchanges with RU1458, JA1729, BR669, 52462691, and 52462693.
