You both got it ! There are two solenoid units on the fire wall right side with power leads and vacuum lines. When the A/C is activated it sends a signal to one of these and it opens to kick up the idle. Power steering pump also sends signals ( or is it the rack ). Not the best at delivering the needed idle bump though IMOP Dave Creasy '85 Westy '93 EVMV '98 Beetle -------------------------------------------------- From: "John Rodgers" <inua@CHARTER.NET> Sent: Saturday, August 21, 2010 12:33 AM To: <vanagon@GERRY.VANAGON.COM> Subject: Re: a/c loads the system down and it stumbles and dies
