There is no relay.....there is a motor controller. located in the duct work, on the firewall, passanger side. it has two connectors and 3 screws that hold it into the ductwork. Common problem is the fan will not shut off when the ignition is turned off.

The blower module is just above the blower motor in the heater case on passanger side about six inches away. Goes in from the top.
SOURCE: Where are blower resistor and relay located on 1995 Park Avenue?
For most common location, open hood and look near cowl for a plug near the air conditioning box just forward of the windshield wipers. It should have several wipers and the resistor itself protrudes downward into the box held in place with two screws. Screws have 7mm, 8mm, or 1/4 inch hex head.
If not: look near blower itself under the dash on the passenger side. The resistor should protrude upwards into the HVAC housing near the blower.
Testimonial: "That was quick! Thanks! Perhaps in passenger compartment versus engine compartment!"

Hi,
By saying it's not the switch, can I assume you have power to it? Or are you hooking the battery to the switch?... I was going to suggest checking for a blown fuse.
