: first of all, the symptoms
: motor starts up, sometimes a/c will enguage immediately sometimes not. after enguage occures it runs for a random ammount of time (with the a/c and fan switch on of course) until the idle goes high from 1k>2k rpms 5secs or so later it disenguages the clutch as well as the radiator fans for the a/c. idle does back down, attempts to reenguage, fails and disenguages, trys again and repeats the cycle. sometimes however it works just fine without the cycling. difficult to predict.

: diagnositics done so far
: no bubbles in the view window
: relays are working properly
: a/c clutch operaters correctly
: both amb air temp sensor and dual pressure sensors appear to be working correctly and get a reading
: TPS...apon is connection and testing resistance it was found that that switch is open all the time, reguardless of throttle position. however after starting the motor with the TPS disconnected, problem persisted.

: now i have no clue

- AFAIK it hasn't been touched since manufacturing nm Alex (90se5spd) 21:03:07 6/24/2002 (0)
