Cruise control will not engage. I hvae checked the fuses and they are fine. There is a part next to the vacuum line that I replaced before that fixed the issue but I don't remember what the part is called.

Catherine, Check your cruise control fuse as a first step. Could be a bad brake switch, faulty vacuum line, faulty multi function switch,etc., may have to have a good Tech. diagnose and estimate repair.
cruise controls have to go through a series of sensors and switches before they work
brake pedal sensor , clutch pedal sensor if manual, VSS sensor, rpm (ignition module) control on switch,fuse,
one or a combination will not allow the cruise control to work
In that vehicle, the usual culprit is a leaking vacuum line. Also, check the operation of the brake pedal cancel switch by pulling upward on the brake pedal with the toe of your shoe while attempting to engage the cruise control. If the cruise control engages, adjust the cancel switch.
Hi Mel, I'm glad to help! The most problems we have found here at the dealership is vacuum problem. Check the vacuum line going to the cruise control unit under the hood. Start the engine and let it idle. Next unhook the vacuum line at the unit and place your finger over the hose to see if you feel vacuum. If you don't the find the crack or where you have lost the vacuum. If it does have vacuum. Then you'll need to see if you have power to the Unit under the hood. Remove the connector and check for power, If you have no Power then replace the brake lamp switch. If you do have power then its a possibility the PCM is seeing something it doesn't like and is not providing ground to the unit or the PCM may be the problem. CAUTION: Do Not replace the PCM unless all other possibilities have been checked and repaired first. Note: Again vacuum problem or the most we have found to be the problem. Hope this helps and have an awesome day Mel.
If your light comes on but the cruise control does not engage you may have a vacuum leak some where. When you set your cruise control your vehicle uses vacuum to maintain speed and if you have a vacuum leak this can not happen. Try checking all of your vacuum lines. I hope this helps.
A vehicle speed sensor provides a signal for the cruise control and also for the ABS braking and the overdrive function. I would start with finding the fuse for the cruise control in your owners manual. Also some cruise controls have vacuum lines attached, if so, check for cracked or broken vacuum lines. Good luck.
well the first thing is to check all your fuses, then i would take a look under the hood for any broken or disconnected vacuum lines,this is what i would check first, hope this is helpful.
