Mine has never turned on during full warmups in the garage, I've ordered up a 'working' one to include the mount bracket and relay from a CA salvage yard...but where does the damned thing mount? I've been through my Parts and Illustrations Catalog about 5 times and can't find it. Maybe my dumbass is skipping a page somewhere. I know I could just backtrack from the tubes and tear crap apart, but I like to see what I'm diving into before actually diving. Thanks.

If I remember correctly and you have AC in the car, that fan should turn on when you turn on the AC. Otherwise I think you can get to it under the truck carpet liner.

This is correct.
It appears on 1985 - 1987 V-6 cars only.
Passenger side of the trunk compartment, under the carpet in the corner.
It is triggered by the FAN switch on the engine, or by turning on the A/C.
Check the relay on the unit before diving in for replacement.[This message has been edited by olejoedad (edited 12-20-2025).]

Misinformation. It's been stated here many times over the decades why the 88's don't require the trunk fan for the 2.8, and why the 85-87's do.

BTW - The '85-'87 Pontiac Fiero Service Manual calls it as "Engine Blower Motor and Relay"
If you have a PFSM, the motor and the relay is shown in Section 8A - 201 - 9 / Figure C
'85-'87 Fan / Blower Circuit
