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 the brake control switch situated just above the break pedal arm under the dashboard. Could be a wire loose or unplugged or the switch itself could be faulty

Check your Fuse holder for the brake light fuse. Its likely it[the fuse] blew.

Its usually a 15AMP fuse, as for the literal location of the fuse box check any of the following places: Under your glove compartment(by the footwell) or the drivers side footwell... .or under the hood.

This is a good fuse:

Check the brake fuse in your dash's fusebox. Since the turns work, you know the bulbs are good, unless your Neon has separate brake lights. If the fuse is good, bulbs are good, then check for power at the brake light switch on the upper portion of the brake pedal. Should have 12 volts there all the time. Use a testlight or voltmeter to check. Good luck.

Did you check the fuse? Either the fuse may be out, or the brake light swith on the brake pedal may be out or need adjusting. You should have 12 volts at the brake switch.

check for a bad brake light fuse! if not the fuse, the brake light switch operates brake lights and if bad you will not be able to shift it out of park, as well as the brake lights not coming on.! because you have to put foot on brake to do so. if bad switch, it wont let it out of park. it could be just out of adjustment also!! good-day !

For your brake lights...First check your fuses...next check your brake light switch..that would get your brakes lights working..Now cem control unit??? Do you mean (Climate Control Unit)??

• If there are no brake lights period the check the stop switch (brake light switch)
• This is attached to the upper part of the brake pedal itself. Should be a little wire off of it. When that goes bad the brake lights will not work at all.
• Please note that the fuse for "brakes" is ABS only and has no bearing on the brake lights themselves working.
