[Gerald Mauricio 2]

Hi guys!



I have a question and hopefully a answer how to correct this problem.

I notice this humming sound since last summer everytime i turrn the ac on i heard a humming noise. its not that loud but really noticeble when radio is off. I think its coming from the condenser.Any Idea how to resolve this issue? Thanks a lot!!!

what tune is it humming?:bwahaha: just kidding! check the blower motor,you might have a leaf or a piece of paper thats caught in the blower wheel.

Mine is doing the same thing. I had something similar happen when I had a Tbird and it turned out to be A/C clutch. I really need to get it in before it starts getting warm down here.

Its coming from the A/C clutch. When i replace my serpentine belt the other day i notice its erevy time the condenser clutch spin the humming sounds kicks in. And if its only the blower/fan there is no humming sounds. Is there anyway to clean the A/C clutch? thanks!

Good luck. Some are very easy. Some are not easy.

The "blower moter" quit on me. It is located in the engine compartment on the passenger side of the firewall. You have to remove the coolant tank/windshield washer reservoir to get to it. The workshop manual shows how to remove it, but I can't find anything in the shop manual that goes deeper into the blower motor. I wasn't a difficult job. I would say, once you have the part, it is about an hr. & a half job or less. About 1-2 beers. :grin::haveabeer:

I think on my Tbird it cost about $200 to have the shop (not dealer) do it. I have most tools needed, but I don't have the gear puller and the adjustment tool so I figured it was worth the cost.
