I can't remember and too lazy to look it up but which speed comes on when you run the air conditioner?

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.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Any recommendations for a radiator fan? I getting tired of the loud fans and want to replace them. Or maybe I'm asking the wrong question. Are they just loud fans? Thanks.

POST 2Original post

If by loud you mean the blades moving air...then yes. If you have motor/bearing noise or some other noise may be something more. If they sound like prop noise of a WW2 era B-25 Billy Mitchell bomber at 1/4 throttle and 1/4 blade pitch then that would be normal. Seriously do a recording of the fans at fan level and post here. They do make noise though...

POST 3Original post

You probably need new low speed fan resisters, common problem.( Google it ) When the low speeds are working properly, the high speed "loud " fans rarely ever come on...

Low speed, but if A/c condenser pressure gets over 400psi (due to high temp) the high speed will kick in.

POST 6 / ORIGINAL POSTEROriginal post

Thanks for help. I'll investigate the resistor. Thanks again.

I don't know (yet), but I would think that if the radiators have not been cleaned and have a lot of leaves stuck in them, they might run a bit louder (in the same way a partially blocked hose on a shop vac causes the motor to spin faster). My fans are fairly loud also. I just got done cleaning the radiators (there was a lot of crap behind the condensers), but I have not put it back together yet, so I don't yet know if they will be quieter once it's back together. Maybe others can chime in on whether radiator cleaning has had any effect on fan noise. .

This thread looks like it discusses the low speed resister in detail -> https://rennlist.com/forums/996-foru...-resistor.html
