Strange sound from the glovebox area - clicking relay?
Hello,
I have a strange sound that comes from behind the glovebox area in my 8. (2005 GT 6MT) The sound is like a really rapid click, more than once a second or so - not super loud, but definitely not quiet. It clicks for a few seconds and stops - sometimes it starts again, but usually it's quiet after the first batch. The sound happens only when I am starting the car - to be clear, I don't need to actually crank the car, even just turning it to the ON position does this. If I turn the car ON, but don't start it, it'll click for a bit, and then stop as I said above. Then, if I crank the engine, she starts fine and doesn't make any unexpected sounds. It doesn't happen every single time I start the car; I haven't been able to nail down a pattern yet, though it seems cold starts are more likely to cause it. Leaving various accessories on or off when stopping the car (fans, A/C, etc) don't seem to affect it either way. My limited troubleshooting knowledge makes me thing it must be electrical, and that it's probably something like a relay. But before I take the glove box apart, does anyone have any suggestions for me? Thanks in advance! :smoker: |

Is this serious? Can it cause damage if not fixed quickly? Any ballpark on price, and how difficult it is to do? |
From my quick reading, the air pump seems to be more of a high pitched buzzing sound, and it happens when actually cranking the engine (for one minute or so, from a cold start).
This sound happens before the actual cranking, so it's almost certainly something electrical, right? There's no vacuum or anything mechanical spinning at that point. Any other ideas? |
The RX8 Air Pump puts extra fresh air into the exhaust system during start up. It mixes with the fuel in the exhaust and causes a lean condition in the catalytic converter warming it up quickly for pollution control.
It was just a thought. Not sure what's behind the glove box that might cause such a noise. Have you tried changing the interior air control to fresh air and back to recirculated air to see if the noise occurs? |
I'll give it a shot - it's almost always on outside air. You think it might be some sort of electrical thing that controls whatever baffles inside of the air tubing?

Multiple fast clicking can be a relay.

The American version does not have DRLs. First thought of a click like that though is a short causing a circuit breaker to flick back and forth. Used to have a similar issue on a Celica with my headlight motor.

OK I can confirm it's got to be something to do with the DRLs because I was sitting in a dark place, started the car, and saw that on each of the clicks I heard the car's running lights were blinking on and off, despite the E-brake being up which normally kills the DRLs from being on.
So, what is my next step to troubleshoot this? I figure I'll take the glovebox off, sure, but what sort of a thing am I looking for in there? |
