its behind a vent so it is something that should be there. it seems to suck air into it for some purpose. if nobuddy knows i will get a video...
Hit the dash above the vent , that outa do it. If not report back and someone else may pipe in, it won't be me.
LOL..my 02 does the same. That little vent to the left of steering wheel. I can change the humming pitch by pressing my finger on it. But Im driving with a slipped liner so who cares!
air temp sensor fan? the A/C uses it to pull air across a sensor to determine the interior temperature.
This is correct. One of my DII's did the same thing, but I never bothered to replace the fan.
why would it come on when the air conditioner isn't on. in fact, it comes on when the entire climate control system is off??
I don't know why, but that's just how it works. There is probably an explanation in the workshop manual.
It is so that you have something else to worry about once the transmission has locked up.
Just fixed this on my 2000 this afternoon. Takes about 5 minutes to pull it out. It's held together with 2 screws, take them out pull the impellar out, clean it all really well with CRC electronics cleaner, lightly grease the two spindles on the impellar (I used singer sewing machine grease), re-assemble and another 5 minutes to put it back in the truck. Completely silent after that. After seeing what the prices are on this, I'd say it's worth 30 minutes to an hour at most to clean it.
I ended up doing it twice, the minute touch of grease made the difference, we'll see how long it stays quite, but it took about 12 years to start making the noise the first time.
