Default Strange BUZZING when Cruise Control Is on?

Hey there guys,

I tried searching to see if this is a common issue or if there is something I can do to fix this.

Problem: When I activate my cruise control there is a strange buzzing sound, not too loud (I can not hear it when the radio is up)... but also not too quiet either. (it is audible enough to hear without straining to try to listen for it)

Any idea as to what this could be? As soon as I turn the cruise control off the sound goes away.


Also, on a non-related issue, I've got random squeeks coming from the dash area when going over bumps and stuff, not super loud.. just annoying at times, is this common? Any way to prevent it?

Thanks!

With the cruise 'noise' is it a constant? I am dealing with a similar sound, it happens mainly when tha engine is under load. Sounds like it is coming from the lower left side of dash?

The plastic gas pedal is picking up vibrations through the throttle cable. When driving w/o cruise, the pressure of your foot on the pedal prevents the noise.

That simple? Mine definitly 'appears' to be coming from the e-brake area.

HUM..... I'm not sure about the speed... I'll have to check, but last time I was cruising with the cruisecontrol on. it was just a steady 60mph pace on the highway, and it was a steady humming noise. Didn't sound like the pedal vibrating, it sounded more like it was an electrical humming vibration kinda noise from right inside the steering column area.

It's easy enough to verify. The next time it happens, rest your foot lightly on the go pedal to see if it stops buzzing.

I'll try this tonight and let you know.
If the noise does stop how would I go about fixing it?
If it doesn't stop, what should I check next?

Many other Ranger owners have noticed this buzz w/speed control and it seems to affect 4.0 owners in particular. Maybe if the very light weight plastic pedal was a little heavier or maybe if the free play in the cable was slightly different, it might help. I don't know the answer.

I haven't had to fix this problem on my Ranger, perhaps because it doesn't have a stock Ranger pedal (it has a Bullitt Mustang pedal grafted on to the factory arm which makes the whole assembly heavier than stock).

Who makes Replacement pedals for the ranger? Are we talking just the end foot placement piece, or the entire moving pedal arm?

The Ranger arm, pivot and pedal is all one piece of plastic. I don't know of any company that makes a replacement.

Reviving an old thread. On my 2002 Ranger, it is definitely the gas pedal buzzing when the engine is under load and the speed control is on. Other than keeping my foot on the pedal, how do I fix it?

Just thinking out loud a little, maybe something can be done with a couple of o-rings. That would allow the pedal to flex, but not rattle.

Take a look at my AC Vent Fix on my profile photos. Maybe that will give you an idea.
