Dashboard Chirp
#1
Dashboard Chirp
07 XK Convertible
I've got an annoying chirp somewhere in the dashboard that sings softly, but discernibly at start up and intermittently thereafter. Once the car is fully warmed up and has been running for 10 or 15 minutes, it seems to stop. It sounds like a fan that's hitting its housing and at some point either the fan stops or seats itself back into the housing without detectible contact after a while of driving.
It sounds like it's to the right side of the center unit where the navigation system/display...almost behind the left part of the glove compartment...then again, I'm partially uncertain of it's exact location since echos bounce in crazy directions in the car.
Anyone else hear this? Is there a solution without tearing the car apart?

I looked closer at it, it's the bosch blower that's right in front of the reservoir. There are two screws on the bottom, I wonder if adjusting the screws might eliminate the chirp.

I did follow the instructions on one of the pages here and "blew out" the drain (it drained properly) and the chirping seemed to be a little less frequent, but I drove downtown today and the chirp got louder and very bothersome.
On the way home, I stopped and got a torx wrench as someone else on this forum suggested, gave the left screw a light tug (1/4 rotation) to loosen it a bit and now it's quiet as a church mouse. Apparently, it had been torqued too tightly and caused enough deformation in the housing so that the fan was scraping a little against the housing which was causing the "chirp". With the screw a little looser, it's fitting in the housing just right and not generating any noise.
