I replaced both from a wreck with 60K miles on it.

That's the thread I used when diagnosing my non-working fan(s).

Suspected cause · Original poster
It's really hard to tell where noises come from at times, but it seemed to be in the front half of the car, so an engine related cause is not on the suspect list at this time.

Should my next step be to check the high-speed fan operation?

Only problem is getting at the fan in order to apply 12V; so your choice is between taking the car apart to test the fan, or plugging in the Durametric system and clicking on an icon.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I'm in the Tampa Bay area of Florida, so bear that in mind when it comes to temperatures. My wife had the Boxster out, and when she arrived home, as she was pulling into the garage, I heard a fairly loud, high pitched whine. It sounded similar to a dentist drill. It's the first time I've heard it.
I immediately ruled out the SAI, as I can't imagine that would be running with the car at full operating temperature. Turned the car off, the whine immediately stopped. I didn't have a chance to revisit the issue until this morning. I started the car, and the whine was gone. Turned on the A/C, and confirmed both front fans are operating as normal.
It's really hard to tell where noises come from at times, but it seemed to be in the front half of the car, so an engine related cause is not on the suspect list at this time.
Should my next step be to check the high-speed fan operation? I can do that with a jumper wire at the relay, correct? Can that be done with the ignition off? Which relays specifically control the high-speed fan setting?
If I'm off track, suggestions would be most appreciated!
Thanks!
Sounds similar to what I experienced with my new to me 99. The left front fan didn't work all the time. When I replaced it the occasional jet engine noise went away.
First... you should identify from where the whine is coming. Run the car and, with two people, listen for the whine fron the front, middle, and rear of the car.
Yes. The fans can be jumped from the relays. I replaced both fans (one? I forget.) and don't recall if I had the ignition in the off or accessory position. Do a search upon this forum... I believe I covered my challenge and certain of the details may be covered therein.
Find the source, first.
If it is a fan... easily you can access it (either one) with wheel removed then peeling back the fender well liner. If you need a fan let me know. I saved the one that wasn't "bad". I replaced both from a wreck with 60K miles on it. My car at the time had ~128K.
Best wishes.
Thanks gang...I'll have to see if it returns at some point. I was going to see about testing the high speed fan operation to determine if that's where the noise was coming from.
Only problem is getting at the fan in order to apply 12V; so your choice is between taking the car apart to test the fan, or plugging in the Durametric system and clicking on an icon. I know exactly where I would fall if faced with that choice.
Did you forget Mothers Day?
Particlewave has good instruction in the attached thread for relay identification and jumper points.
