where is the 2002 oldsmobile alero cruise control vacuum line?
Usually part of the switch (module)
To change the passlock module on a 2001 Oldsmobile Alero, first disconnect the negative battery cable to ensure safety. Remove the steering column cover by unscrewing the necessary fasteners, then locate the passlock module, which is typically positioned near the ignition lock cylinder. Disconnect the wiring harness from the module, remove any mounting screws, and replace the old module with the new one. Reassemble the steering column cover, reconnect the battery, and follow any reprogramming steps necessary for the new module to function properly.
The manual says to turn on the ignition.
Turn the ignition key on for 10 minutes and it will reset.
you need to re-do the timing of the ignition system. the other possibility is the ignition is worn out and needs to be replaced.
The ignition module is right underneath the ignition coils. The ignition coils are what the spark plugs attach to. My alro was riding really rough so i just changed my coils and module for $200 and it runs like new. All you do is unplug the wires, unscrew the coils(6 bolts) and there is your module. :) Hope this helps!!
