Hey All,

I have a 98 with Digital climate Control- I noticed lately that when the heat is on I hear a whistling- When I turn the climate control off it goes away, so clearly it is only occuring when the fan is on- I don't hear the whistling sound(almost like a loose bearing?) when the fan setting is on the 3rd and 4th level, meaning the more powerful fan settings?

anyone ever encounter this problem- It's really annoying!

Thanks for any help

Hey,

I've had 2 Maximas (both 4th gen ones) and the fans have squeaked/whistled a little on both of them. It only makes the sounds loud enough to be annoying on fan speed 1, but makes it very slightly on fan setting 2 as well. Since I've noticed it on both Maximas, I have always assumed its normal. I doubt there's any way to get to the fan in there and quiet it down. It's never affected performance in any way...
Hope this helps - Chad

I guess I'm lucky, then. My climate control blower works very quietly, unit I get to fan speed 3 or 4, but that noise is just due to flow.

Yep. And not just in my car. It almost sounds like there's something stuck in the blower or it's slightly out of balance. Just enough to make noise at low speeds but not at high ones. I just learned to ignore it.

Trace the sound and oil the cause.

Or ask it to whistle a different tune, like dixie or something

My 99 GLE had this problem. I noticed it when I was test driving, before purchase, and worked the repair into the deal. They had to replace something, not sure exactly what it was, but there's a TSB out for this so you should go look that up.

Ok, I just bought a subscription to the Maxima TSBs (at alldatadiy.com), so now I have data for anyone wanting to fix this.

The TSB for this problem is NTB99-071A. Basically, all the TSB says is to install a new blower motor cover, which is part number 27227-0E002. That's if your climate control makes a light ticking or humming noise while on fan speed 1 or 2. If there's a loud rattle, clatter, jolt, or flap, then you probably just need to clean the blower case.

If anyone wants a copy of the TSB itself, e-mail me at bodziana@hushmail.com and I'll see what I can do.
