My 2004 jetta cruise control is not working. I have changed both the brake switch and the clutch switch and I checked all the fuses. What else could it be?

has a fuse and an actuator motor or
the set resume switch could be faulty

faulty brake light switch , or fuse ,, check your brake lights , if dont work change fuse and if that dont work change the brake light switch

check cruise control fuse and check the brake lights see if brake light working because the brake light switch will deactivate cruise control when brakes is applied.if brake lights dont work either fuse blowed or switch bad.if all is good have vechicle code scan because cruise control control by PCM and vechicle speed sensor and thottle actuator control motor.

Check all your ground points. The brake lights and cruise may be grounded to the same spot. Re-check the cruise fuse and brake/tail light fuses.

There is actuly 2 differant fuse #12 the brake fuse #12 10 amp and fuse #1 the stop and haz 20 amp .But neighter are likely the problem . There is another brake switch for the cruise control called the TCC brake and cruise control relese switch that tells the transmission when the brake is applyed and shut of the cruise control . This is more likely the problem its up under the dask near the steering colluom follow the wires from the main brake switch on the pedel if you have a standard then it will run through the clutch switch as well .Fuse #12 also controls the muilty function switch but fuse #1 is the brake input switch . So if the lights and blinkers work i would look at the TCC brake switch first thank you

CHECK CRUISE CONTROL FUSE. IF FUSE GOOD PROBLEM IS IN THE SERVO MOTOR THE CRUISE CONTROL MODULE VACUUM PUMP AND CLUTCH VENT VALVE THE BRAKE VENT VALVE AND VACUUM SIGNAL AMPLIFIER.YOU HAVE TO TAKE CAR TO DEALERSHIP THEY HAVE EQUIPMENT TO FIX IT.

Start with the simple and check the fuses and the Stop lamp switch. Check your brake lights, if they're not working, the cruise won't work either. If they're not working, check the fuse for them, if the fuse is fine, then take it into the dealer, there's been a recall issued on the brake switch, so it should get fixed for free.
Cruise Control Disengaged
The powertrain control module (PCM) disengages the cruise control operation based on the signals from the following switches:

* The stop lamp switch
* The TCC brake/cruise release switch
* The clutch release switch, if equipped
* The cruise control On/Off switch

The TCC brake/cruise release switch and the stop lamp switch are mounted on the brake pedal bracket. When the brake pedal is applied, the normally closed TCC brake/cruise release switch opens and the normally open stop lamp switch closes. The PCM detects a low signal voltage on the TCC brake/cruise release switch signal circuit and a high signal voltage on the stop lamp switch signal circuit. When the clutch pedal is applied, the normally closed clutch release switch opens and the PCM detects zero voltage on the CCP switch signal circuit. The vehicle speed stored in the memory of the PCM will be erased when the cruise control On/Off button is turned OFF, or the ignition switch is turned OFF.

The Cruise Control System will disengage when the PCM detects that a driver override function has been active for approximately 60 seconds .

When the Cruise Control System is disengaged, the PCM sends a class 2 message to the instrument panel cluster (IPC) in order to deactivate the cruise control indicator.

Cruise Control Inhibited
The powertrain control module (PCM) inhibits the cruise control operation when any of the following conditions exist:

* A cruise control related DTC has been set.
* The vehicle speed is less than 40.2 km/h (25 mph) .
* The vehicle is in PARK, REVERSE, NEUTRAL, or 1st gear.
* The engine RPM is too low.
* The engine RPM is too high, with fuel cut off.
* The vehicle speed is too high, with fuel cut off.
* The system voltage is not between 9 volts and 16 volts .
* The Traction Control System (TCS) is active for more than 2 seconds .
Thank you for using Fixya and start with replacing the stop lamp switch. Even though the brake light work, it;s been known for that switch to cause your issue. that's way there was a recall for it.

There are 3 places on the Rav4 where fuses can be located and checked. for the cuise control.

The back of the cruise control stacking switch has been know to fail (fall apart) and Toyota issued a TSB with replacement switch.

if it is the fuses then they most likely are related to cruise control system: Stop, Dome, Gauge and Igniton
The interior fuse box
The main engine fuse box (by brake fluid)
Cruise control ECU is under the glovebox.
Cruise control actuator is under hood (by driver side brake fluid/booster)Throttle position sensor (to detect if your foot is on gas pedal)
Cruise control switch on the clutch pedal too (if you have 5spd manual)
Brake lights are the deactivate signal for the cruise control

I would check the easy things first. That is the brake switch and the clutch switch (manual trans). Drive down the road and pull the brake pedal up with your foot and then try to set the cruise (same with the clutch pedal). Also the cruise requires that the brake light bulbs be in working order (and that there are no LED brake lights). Check fuse numbers 53 54 and 59.
The high beam problem might be related to the cruise issue, but I can't think of a reason why.

here are two switches that are the usual causes of the cruise kicking out. they are both under the dash. One is the switch for the brake lamps (stop light switch). the other is for the clutch if you have a manual transmission.

if you follow the brake pedal up under the dash you'll find two switches at the top of the pedal. (it may be one switch but I think its two). the top one would be for the cruise control. if the switch is loose it will cause the cruise control to think you're stepping on the brake and that will disengage the cruise control

same with the clutch pedal if you have a manual transmission; if the switch is loose it will indicate you are pushing the clutch pedal in and cause the cruise to kick out

other than that you'll have to check all of the connectors. If it does engage then the fuses and actuators should be good and it would be a loose connector or switch that's kicking it out

also, i assume your speedometer works; if its not then that's your problem as the cruise won't engage under 30 mph
