I am the original owner of a 1985 V6 SE body and during a search for parts came across an ad for a used trunk blower motor. I had no idea what that was until I looked into this further and was surprised to learn that some Fiero's had this feature. Again, I am the original owner so nothing was ever removed from the car - its is purely stock. My car does have the 2 tubes mounted to the engine side of the trunk metal, and for years I wondered what they were there for. So, my question is when exactly did Pontiac start incorporating the trunk fan into the production of the V-6 versions?
The car was driven daily when I first bought it and thereafter for about 10-years but is now just part of a collection of other vehicles I own. I never had a heat issue when it was driven daily.

Rear fan turns on same time as the radiator fan.
See my Cave, Rad Fan
Used for 85-87 V6 as aux cooling for things it blows on... the alt & ignition parts.
88 deleted this mainly to save cost for GM and upgrade the alt from SI type to CS-130 so don't read is good for you to remove it.------------------
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.

Thanks for replying. I knew that is was supposedly used for those model years. My point was that as the original owner my car did not have that setup. It has the tubes for the coil/distributor and alternator but no other plumbing inside the trunk. This must have been a running change and not implemented on all of the production. The cars was well maintained and if it was a matter of a recall, I would have known. I don't see any other explanation.
I do think it was a good approach for cooling those components because I did have a recent issue with the control module inside the distributor. I went through 3 of them and I suspect heat was and issue. I'm in the electronics manufacturing and fully understand the affects of heat on components.[This message has been edited by TOM SUTCLIFFE (edited 05-24-2021).]

Only big "Plumbing" is the blower and maybe a duct under the right side trunk carpet. You have the 2 pipes then something is wrong. Maybe made wrong at factory or after. If "ripped out" then then still have wires and patch/plug sealing hole(s) in the trunk where sucks air in.
Fire Recall does not remove the blower.
See my Cave, Do You Recall?
Most ICM's etc are "Automotive Grade" parts close to "Mil Spec" electronics to handle engine bay heat. IOW They take heat much better then most anything made for normal consumer environments.
Most repeat fails of ICM isn't heat but something else. Highlights...
See my Cave, HE Ignition
HEI and some others ICM need Heatsink Grease and good clean hardware to mount them.
Many come w/ silicone grease, does help but not as good.
Note: Many claim Fiero Engine bay gets hotter then others is a myth. I tested this ~ 20 years ago but limited to basic tools at the time and why the cave doesn't have crap to cool the bay.
Then tested more now because easy to make a data logging temp w/ multiple sensors of different types at same time.
Some results are in Fiero Engine bay vs Heat. https://www.fiero.nl/forum/Forum2/HTML/141784.html

Whether you've been aware of the blower or not, I suspect it has been hiding (and still is) in the corner of your trunk for the last 36 years.  [This message has been edited by Patrick (edited 05-24-2021).]

I'll be a SOB!!. I just peeled back the carpet and it is there. I'll have to see if it comes on with the radiator fan like it's supposed to. It must be a very quiet sucker ( or burnt out) because in all the years of driving and working on the car I have never heard it run. I don't remember seeing it in the factory shop manual either.
Thanks for being persistent and setting me straight. I have a bunch of cars, 2020 vette, 63 vette, 62 VW Beetle, an 09 SRT8 Jeep, and the 85 Fiero. I've been tempted to sell the Fiero more than once, but when I take it out to drive I always change my mind. GM really missed the boat on that as it could have evolving nicely as it did until they pulled the plug. The new Vette is the 1st car in a very long time that GM got right.

That's all that really matters. You're A-OK in my book.
