How to work cruise control on 2002 alero oldsmobile

It's probably a problem with cruise control module , located under the hood in engine compartment . Or a bad connection somewhere . Do you know how to do electrical testing ? Is the air bag light lit on the instrument cluster ?

Could have DTC'S - diagnostic trouble code's stored .
DTC P1554
The powertrain control module (PCM) inhibits cruise control operation when certain conditions are not appropriate for cruise control operation. The PCM removes the ground from the cruise control inhibit signal circuit in order to disengage cruise control operation.
DTC P1585
Output driver modules (ODMs) are used by the powertrain control module (PCM) in order to turn on many of the current driven devices that are needed to control various engine and transaxle functions. DTC P1558 set indicates that an improper voltage level has been detected on the signal circuit which controls the cruise control inhibit circuit.
Action Taken When the DTC Sets
• The PCM will not illuminate the malfunction indicator lamp (MIL).
• The PCM will store the conditions present when the DTC set as Failure Records data only.

Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions. However, steep grades may cause variations in the selected speeds. The electronic cruise control system has the capability to CRUISE, COAST, RESUME SPEED, ACCELERATE, and TAP-UP or TAP-DOWN.
The main parts of the cruise control system are:
• The cruise control module assembly
• The function control switches
• The cruise control release switch
• The clutch pedal position switch (CPP), if equipped
• The stop lamp switch assembly
• The vehicle speed sensor
The cruise control system uses the cruise control module assembly to maintain the desired vehicle cruise speed and operation. The cruise control module assembly has an electronic controller and an electric stepper motor to vary the throttle in each different cruise control mode. The electric controller monitors vehicle speed and operates the electric stepper motor. The stepper motor operates in response to the electronic controller, to maintain the desired cruise speed. The electric stepper motor moves a strap that is attached to the cruise control cable which moves the throttle linkage. The cruise control module assembly contains a low speed limit which will prevent system engagement below a minimum speed of 40 km/h (25 mph). The module assembly is not serviceable.

replace cruise control module

you have 2 fuses, one under the hood fuse #46 and one under the dash fuse L, both are 10A, if they are both good replace your control panel.

The 2004 Oldsmobile Alero is a very reliable vehicle. It averages a 6.1 on the steering, handling, and braking tests.

Yes, there is a fuse. Could be the vehicle speed sensor, could be a bad wheel bearing, could be cruise control switch, could be transmission control module, could be brake light switch.

Is it winter and icy where you are? If so you should never use the cruise control on icy roads. Exactly what you described happens because one tire will brake loose on the ice and the car doesn't know what is going on. It can't regulate the speed.

there might be a problem with your brake system. If there is it wont allow the cruise to work. Hope this helps alittle

use a scanner to check the abs system . most of the time the abs brakes and traction control system work together. your cruise control . unit has a servo motor .in front right fender well. check the fuse and relay also the cruise control brake release switch. and the brake light switch.if all is good you have a cruise control module problems. dealer ship job.

replace switch.

if it worked before i would chk. the fuse, there will be one for it, but if its blowen something made it do it. i would replace it, and if it blows again, you will have to find the cause, could be switch.
