Oldsmobile alero 2003 v6 how can i fix the cruise

replace cruise control module

try this site. Fix Cruise Control Switch Olds Alero and Others

Try checking the small switch at the top of the brake pedal. There may be two one for brake lights and one for the cruise control. To ascertain what is what, pull one wire off and see if brake lights work. If not, then the other switch controls the cruise control disconnect and engage..I you have a DC test light check to see if power is on on both side of the switch with brake pedal up. If so, depress pedal and check power on the other side there should be none, if there is the switch is defective.

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

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

they should turn on at about 213 orbetween 200 and 215 dont let it go over 230 if so please turn off

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.

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.

Use Valvoline 10-30. Manufacturer Recomended.

Found out what it was relay switches. (Fuses)
