HVAC Fan / Blower Cuts In and Out

[dbs600]

Hi everyone,

Hope all is well.

I had this problem a while ago: https://forum.ih8mud.com/100-series-cruisers/538582-hvac-fan-blower-chirping-screeching-sound.html and didn’t do anything to fix it. I would have added to the thread, so not to start a new one, but the thread is now closed / locked.

Nevertheless, I now have the problem where my HVAC fan / blower cuts in and out and does not constantly stay on. With the problem as described, would replacement of the part I removed and took pictures of in the prior thread fix the problem?

AND, if so, where is the best place to get a good priced new replacement?

Please advise ASAP, as it’s getting hot here in NY.

Thanks!

Hi again,

I called my dealer's parts department today, gave them my VIN and described my problem.

Unfortunately, they said there are several parts involved with what I am describing, including: the "Motor Assembly", "Servo Motor Assembly", "Control Motor Servo" and “Amplifier".

While the dealer was vague, can anyone please shed more light on this, including what the differences between the various parts are and which part is most likely to apply.

Thanks again!

Is there anyone that can shed some light on the above? Thanks!

I'd start by taking apart the blower and cleaning it out, make sure the contacts on the connection are good.

I bought a used one from lkq auto parts about 30k ago for $75 to replace my squeaky one.
