Chevrolet Citation HVAC Blower Motor High Speed Relays

Chevrolet Citation Hvac blower motor high speed relays

Starting at $14.95, AutoBuffy stocks 1 HVAC blower motor high speed relay options from Standard Ignition for your Chevrolet Citation. This relay controls the high-speed setting of the blower motor fan. When it fails, the fan runs only on lower speeds or stops entirely, leaving your Chevrolet Citation without full heating or cooling airflow when you need it most.

Signs your Chevrolet Citation needs a new HVAC blower motor high speed relay

  • Blower fan works on low and medium settings but cuts out completely on the highest speed setting
  • HVAC fan suddenly has no high-speed output even though the blower motor itself is otherwise functional
  • Intermittent loss of high-speed airflow that comes and goes, often worsening in hot weather as the relay heats up
  • Burning plastic or electrical smell near the dashboard or firewall where the relay is mounted
  • High-speed blower stays on continuously and won't shut off, indicating the relay contacts are stuck closed
  • Blown fuse in the HVAC circuit that returns after replacement, pointing to a shorted relay drawing excess current

Which HVAC blower motor high speed relay should you buy for your Chevrolet Citation?

The main decision when buying a blower motor high speed relay for your Chevrolet Citation is whether to choose an OEM-equivalent direct-fit unit or an upgraded heavy-duty relay with higher contact ratings. Connector type and current rating must match your Chevrolet Citation's original specification, so confirm compatibility before purchasing.

OEM-Equivalent Direct-Fit
Best for
Owners who want a straightforward drop-in replacement
What you get
Matched connector, same current rating as the factory relay, no wiring modification needed
Heavy-Duty Upgraded Relay
Best for
Vehicles with a history of relay failure or high blower motor amperage draw
What you get
Higher contact current rating, better heat resistance, longer service life under demanding conditions
Genuine OEM (Dealer-Sourced)
Best for
Owners who insist on exact factory specification and have fewer cost concerns
What you get
Exact OEM part number match, guaranteed fit, typically the highest unit price
Multi-Pack Value Set
Best for
Fleet owners, shops, or owners who want a spare on hand
What you get
Two or more relays at a lower per-unit cost, useful since these relays can fail repeatedly on high-mileage vehicles

Replacing the HVAC blower motor high speed relay on a Chevrolet Citation

Easy⏱ 15–30 minutesFuse puller or needle-nose pliersMultimeterFlathead screwdriverFlashlight or work light

Locate the relay in your Chevrolet Citation's fuse and relay box using the cover diagram, then pull the old relay straight out with a fuse puller or needle-nose pliers. Press the new relay firmly into the same slot until it seats fully, then test all blower speeds to confirm normal operation. No disassembly of the dashboard or HVAC housing is required in most cases.

Frequently asked questions

How much does it cost to replace HVAC blower motor high speed relays on a Chevrolet Citation?
The relay itself starts at $14.95 at AutoBuffy. Because the relay is typically located in the underhood fuse/relay box or on the firewall, installation is straightforward and labor is minimal. Total DIY cost is usually just the part price, while a shop may add 30–60 minutes of diagnostic and labor time.
Where is the HVAC blower motor high speed relay located on a Chevrolet Citation?
On most vehicles, the blower motor high speed relay is found in the underhood fuse and relay center, mounted on or near the firewall, or inside the cabin fuse box behind the dashboard. Consult your Chevrolet Citation owner's manual or fuse box cover diagram to identify the exact relay slot before replacing it.
Can I drive my Chevrolet Citation with a failed blower motor high speed relay?
Yes, a failed high speed relay is not a safety hazard that prevents driving. However, without high-speed airflow your Chevrolet Citation's defroster performance is reduced, which can compromise visibility in cold or humid conditions. Replacing the relay promptly restores full climate control and defroster effectiveness.
How do I test the HVAC blower motor high speed relay on my Chevrolet Citation?
Use a multimeter to check for continuity across the relay's output terminals when power and ground are applied to the control terminals. You can also swap the suspect relay with an identical relay from another circuit in your Chevrolet Citation's fuse box as a quick bench test. No specialized equipment is required.
Why does the blower motor high speed relay keep failing on my Chevrolet Citation?
Repeated relay failure usually means the blower motor itself is drawing more current than normal due to worn brushes, a failing resistor, or a partially blocked blower wheel. If the relay fails again shortly after replacement on your Chevrolet Citation, have the blower motor and resistor pack inspected before installing another relay.
Is the HVAC blower motor high speed relay the same as the blower motor resistor on a Chevrolet Citation?
No, they are separate components. The resistor controls low and medium fan speeds by reducing voltage to the blower motor. The high speed relay bypasses the resistor and delivers full voltage directly to the blower motor for maximum airflow. Both parts can fail independently on your Chevrolet Citation.
