Some times when i drive the cruis control light come on

Chrysler Concorde

get your car fix right now

It's very possible you have a bad ignition switch. My '96 LXi had the same problem, plus it tended to randomly drop into "Limp Mode" at any speed.

After replacing the ignition switch (3 years ago) neither of those problems has resurfaced.

check the rpm and road speed when this happens . The cruise control will increase to keep RPM constant but as the road speed drops the auto may be shifting down and as the rpm increase it shifts back before the rpm adjusts. You can override a cruise control in this situation by simply pressing down on the accelerator to maintain the power setting and road speed and when the situation is passed and you take your foot of the accelerator the cruise control will return the system to the set position without you needing to do anything

Hi, did you already solve this problem with cruis control in european Ford Focus C-Max? I just activated cruis control in my car... It normaly works on 3th and 4th gear (manual transmission). On 5th gear it works only sometimes - I have to put the gas pedal down and then press the "+" or "RES" button, if I cancel selected speed and than again press "+" or "RES" button, the LED of cruis control on the dashboard flash for 1 sec and nothing will happen.

Chances are the check engine light came on also. You should have the vehicle scanned for codes, it could be that the output speed sensor has failed. This could put the transmission into limp mode (second gear) and cause the speedometer not to work. I would guess this to be an inexpensive repair, .6 hours labor plus the cost of the sensor, $16.99 at O'reillys ...I hope this helps

have u run a fault code test on the systems computer, this sounds like maybe a Vehicle speed sensor problem, the speed sensor is on the side of the transmission, but do the code test, here is how u do that, go to the link below for instruction's that apply to all Chrysler cars and trucks

Change your Crankshaft position sensor, or your camshaft position sensor. Same thing happened on my car about 3 months ago.

That is a code for an invalid skim key. If you have another skim key try it. If it does the same thing then the skim module may be bad.

with a 2002 Concord 3.5 V-6, what should the rpm be at 60mph? 70 mph?

I'm not sure if the overdrive gear is lost in the tranny, but the transmission light is on.

Thanks

well what you need is to replace the two sensor on the trans the input and the output speed sensors they less than $30 each and the car will shift again
