Weather related electrical problems

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.

May have to check out if the vacuum motors have the vacuum tubes attached but this may take a lot of work to disassemble the heating ventilation air conditioning out of the dash and underneath the dashboard. If rain enters the compartment under the dashboard, the pan that is designed to catch water may be disturbed or cracked somehow. Try to check fuses for a/c and the heating, the cruise control, and windshield wipers to see if there is an obvious electrical issue there. The vacuum leak is not related to the windshield wiper motor not working.

Good luck on this repair.

There are a few things you can try. First, check your
brake lights, if they do not work the problem may be
in the stoplight sw circuit. Also there are 3 fuses you
can check, 1 is a 25amp in the fuse block under the
hood the next 2 are in the fuse block under the dash.
One is the 15amp stoplight fuse and the other is a
10amp turn sig fuse. These fuses are either directly
or indirectly related to the cruise ctrl. Next check the
cruise switchs accel/coast set/resume if either sw.
was sticking in any posistion for 90 seconds or more,
the cruise ctrl. will shut down. There are trouble codes that will set but they won't trip the check engine light. You'll need an obdII scanner to recover
them from the memory. If you don't have one, go to
autozone/napa or advance auto parts they will scan it
free. The codes of interest are po571 stoplight switch
po567 and po568 the cruise ctrl switch's. And any
other codes related to the torque converter clutch -
the speed sensor - throttle actuator control.
Hope this helps. Good luck.

If I don't remember bad, check the position 15, fuse 15AMP (mini fuse) underdash fuse panel.

Hope solve your problem (remember rated this help).

heve utried adjusting the trottle , just put your foot on the accelerater and hold at just under 1000 revs if shaking goes then thats your problem should idle at just under 1000rpm

I am having the same exact issue right now with my 01 Alero. Been having electrical issues with lights coming on and off. ABS was kicking on a few times even. It started sputtering like it was running out of gas, thought that might have been the case. But after I put gas in it it still didn't start. Now it turns over but nothing. What ended up being wrong with yours?

Hi
Check for wires rubbing against brake pedal linkage under the dash.

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.
