CRUISE CONTROL

2002 Pontiac Grand Prix

2002 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 125000 miles

Cruise quit working one day. Checked the fuse and it was ok. Took it to the shop and was told I need a new cruise control module. First off, where is this module located and secondly, can a wannabe shade tree mechanic handle replacing this? They wanted $359 for the module and another $100 to install. Please help.

CRUISE CONTROL INOPERATIVE/MALFUNCTIONING Diagnostic Aids Conditions for Enabling Cruise Control When vehicle speed is more than 40 km/h (25 mph) When PARK, REVERSE, NEUTRAL, or 1st gear is not indicated. When an over/undercharged battery condition does not exist. With normal engine RPM. IMPORTANT: Perform the following in order to avoid misdiagnosis. Inspect for proper operation of brake lamps. Inspect throttle linkage for mechanical binding which could cause the system to malfunction. Inspect cruise control cable adjustment, should have minimum slack. Inspect for stored Diagnostic Trouble Codes (DTCs) in the PCM. EMI on the speed sensor signal circuit may cause erratic cruise control operation. Module is 2nd diagram with part 2 pointing to it.
