hi all,

1990' Carat - recently purchased - rebuilt engine - smooth idle 950 RPM -
A/C recently serviced, cold air, new fan switch.

When I turn the A/C on the idle jumps to 2000 RPM - the fan goes to medium
speed all the time.

What part or parts that triggers the idle?

What part or parts that triggers the fan?

please help -  I search in the archive and only found an April 2000 article
about this..

many thanks in advance
