1989 e34 weird noises from behind dash

[cowleyci5]

I've recently bought a 1989 E34 525i.....it's a right hand drive, when I unlock it and get into it or turn off the engine, I can hear a strange intermittent buzzing noise coming from behind the dash on the passenger side (right hand drive car)........any one know what this might be??

It's normal. You will hear that about 4-6 times or so. Either from the a/c compressor or the water pump- I forget which.

Hi,

Thanks for that

It's all the motors that operate the various flaps and such of the climate control.
