Ford Aerostar :: Speedometer / Odometer And Cruise Control Not Working

My speedometer, odometer & cruise control quit working and I think the transmission overdrive is also not working on my 95' Aerostar 2wd, 3.0L engine. I replaced the speed sensor that sits above the rear differential, but that didn't work. Wondering if something needs to be reset?

Ford Aerostar :: 1997 - Cruise Control Cable Broken

When I had my heads replaced, the mechanic informed me that my cruise control cable was broken. News to me. It worked fine before. He said he couldn't find a replacement. I went to my local Ford parts dept. and they told me it was a discontinued item.

So I went online and ordered one from Direct Ford Parts and it did not match. The part number was FMC-F49Z9A825JA. In the parts catalog it says it fits 92-97. Not even close. The one I have has a screw off top and the one sent has a bolt on housing.

Ford Super Duty (1999-2016) :: Cruise Control Isn't Maintaining Speed

I was driving home from school last week and noticed my cruise control would stay set for 5 minutes or so, then slowly (over several minutes) lose speed. I've noticed it happen before, but very infrequently and usually if I stopped to use the restroom, when I started the truck back up it was fine. This time it continued to happen.

As I was getting nearer to home, I noticed that while I had the cruise set, I would hear a high squeaking noise in the dash almost dead center under the radio. Then , when I would tap the brakes, there would be a rattle. This would only happen with the cruise set.

Noise in dash - YouTube

Not sure how well the squeak can be heard, but the rattle is definitely audible. What the cause might be? Electrical, mechanical, are the cruise and the noise even related? Other than that, the truck seems to be running alright.

Ford Super Duty (1999-2016) :: 2002 F250 - Cruise Control Turn On But Sometimes Set Speed

Truck is an 02 F250 Automatic 4X4, 7.3 PSD.

Cruise control will turn on, will sometimes set speed and sometimes will not. If it does set and work it may kick off at any second or it may run fine. I have noticed it seems to kick off mainly after going over a slight bump in the highway or it may just kick off for the hell of it. Truck has 50,000 miles on it, I bought it new. Also having trouble with the throttle position sensor, it seems to have a "dead spot" at about 58 mph that shows up when I romp down on the pedal to pass on 2 lane roads. Can these two symptoms be related? Both are very aggravating. FWIW it does have the power adjust pedals. Truck is 100% stock, no power chips or other upgrades.

Touareg :: In Cruise Control Mode, Speed Can't Be Set

My vehicle shows currently two awkward behaviors:

1) I can start the vehicle using the keyless start button without having to step on the brake pedal.

2) I can switch on cruise control. The green symbol appears, however, I cannot set a speed. The system simply seems to ignore that I press the set button.

Lexus LS 2007+ :: Cruise Out Of Control - Sloppy In Speed Regulation

The cruise on my 2013 LS460 SWB RWD sucks big time! Both Dynamic and Normal cruise modes are WAY too sloppy in speed regulation. I was out today on a 55mph PSL two-lane with set speed of 59mph. On a long SLIGHT downhill, the indicated speed topped out at 70MPH!!!

BTW, tranny shifting was weird during this episode with a prolonged run at over 3k RPM. At any rate, that's 11mph over the set speed for the arithmetically challenged. So instead of tooling along at a maximum of 5 over the PSL as my 2007 LS would have done (set speed 59 + overspeed 2 = 61 indicated = 60 actual, so 5mph over PSL), I'm flying at 10mph over the PSL ripe for the picking by any county sheriff (and I saw THREE of them on that road, all with their radar on).

I figure my car's speed regulation (in both Dynamic and Normal cruise) is +11mph/-2mph for set speed of 59mph. That is crazy!

Passat (B6) :: 2006 VW - Cruise Control Current Speed Display

When I first got this car about 2 months ago, my current speed would be displayed in the MFD when the cruise control was set to on (not activated and in use). For some reason now that no longer happens and it just shows dashes. The only time the speed is displayed now is when I am actually using the cruise control. Is there a way to get that thing back to showing my present speed like it did before?

Santa FE SM (2001-06) :: Tail Light And Cruise Control Won't Set The Speed

I have a 2006 santa fe with th 2.7. The tail lights light up both films on both sides when you turn the lights on. Now the cruise control will turn on but it won't set the speed. I changed the brake switch and i tried to put it in the same exact spot. The old one was not sticking or anything. Now I was told the switch might need reset or something. I looked everywhere for shorts and sealed them up. Checked all the fuses which all are good. So im not sure whats going on. Now when you press the brake the small fuse will burn out.

Golf/GTI VI :: Cruise Control Malfunction - Set Speed Number Drop?

Cruise control on, set at, say 65mph. I want to lower the speed to 60mph. Tap down... click-click-click-click-click and watch the set speed number drop to 60.... then pop right back up to 65 and the car accelerates back to faster set speed. This has happened more than once now.

Not sure if this should be under the technical section but is there a way to modify the cruise control to be set to a position on the hsi and not based on the speed. After all it is all electronic.

Sonata I45 (LF 2015+) :: Cruise Control - Transmission Will Downshift To 4th Speed Whenever Go Downhill

The cruise control on my 2013 works as I expected.

However the cruise control on my 2016 Sonata does not.

When driving at highway speeds (65 to 70 mph) in cruise control and the shifter set on "D" (drive) the transmission will down shift to 4th speed whenever I go down hill.

This might be intentional as a way to keep the car from exceeding the set speed, but I have never heard of this and it would seem to place more wear an tear on the transmissions.

Do the down shifting is engineered in or if it is a service problem that I need to have addressed...

Prius (2010-12) :: Downhill Cruise Control No Longer Holding Speed

2012 Prius with 10K miles.

One of the features I really like over the '06 Prius is the ability of the cruise control to hold the set speed on downhills (until the battery fills up and it switches to compression braking "B" mode, but that's a different topic).

After taking it in for the 10K mile service, it no longer engages regenerative braking on downhills with cruise control set. This is on the same hills where previously it would hold speed.

Did Toyota do a software upgrade that disables this feature?
