2nd go 'round for cruise control..Have done all the following diagnostics- checked all vacuum lines for cracks, found none, all hold vacuum. Tested vacuum diaphragm on accelerator pedal, works ok. Checked brake pedal release, works okay also. Removed battery tray, and accessed vacuum pump mounted underneath. No cracks/observable defects in pump, connected it to a vacuum gauge, applied 12 volts to it, it pulled and held a consistent vacuum level. I';m thinking my problem is something electrical, with a sensor or the switch in the turn signal stalk. Can anyone tell me what sensors I have, and how to test them? a schematic sure would be helpful...
