Strange noise from Climate control
I am getting a electrical-shorting/ clickety noise at idle. I have traced the noise down to the climate controls box. Anyone have a spare or an idea as to what is causing this?

Texas,
Are you talking about a noise coming from the mechanism under the hood or the unit under the dash? Pete |

under the dash
under the dash area. It sounds like the unit that controls the blow speeds and the climate is shorting out and it keeps making a strange shorting clicking sound..

Darn! I wish I could help. My cruise control (?) unit under the hood makes a funny "small electric motor" running sound when the key is on. I don't think it did it all along. I'm wondering if it has something to do with the bulbs I put in the REVERSE sockets... I dunoo...

My guess is that the aspirator motor is bidding adieu.

That thing is easy to test - unplug it and see if the clicking continues.
