Hi,
The first time I used the A/C this year, a really strange sound emanated from behind the dash, like a chattering relay. It lasted for about fifteen seconds and then stopped, however, since that day, there has been this chirp that rhythymically pulses every ten seconds.
Image a relay that bounces say, three times. It sounds like that but oddly, there has been no impact on anything else; A/C works just fine. Once in a while, when I turn off the iignition, that fifteen second chattering will happen again.
Listening to it, I would place the source of the sound at about the level where the steering column enters the dash and to the right of it, between the column and radio. Car is US spec, left hand drive (91 535).
Can it be a vent trying to get into position and getting hung up or is it a relay? I'm hoping someone can help identify the possible culprit before I tear up the dash and randomly poke around.
Thanks,
Adnan
