Sometimes it goes like a Bat out of &@!%^ and sometimes not. Should I try changing the I/C pump again or are there other possible solutions? If I do not reply after April 22 it is because I'm on vacation till the 17 of May at which time I'm going to troubleshoot this problem.
Wire up a couple of idiot lights :
1. common ground.
2. one lead to the hot side of the S/C clutch
3. other lead to the hot side of the I/C pump.
use the windshield wiper to clamp the lights.
use different color 12v bulbs.
Then when it stumbles, you'll know what's what.
