Hey guys, my right side speakers ('99 F150) I installed about a year ago quit working last week, and yesterday my cruise control went. Don't know if they're related...it's been pretty cold around here so I'm thinkin that may have something to do with it? I pulled the head unit out to see if the wire harness was loose, no dice.

Any ideas??

 

I dont think the CC and speaker could be related, I just dont see how.

Cold really shouldnt be a factor either, possibly though. How cold?
A few weeks ago it was -15 for a few days, never got above 0 degrees, and I didnt have any problems.

Have you pulled the speaker out to see that its still connected there?
Try that, and if it is, get a Voltmeter and put it on the ohm setting it stick it on the terminals of your speaker. If you get a high reading, or no reading at all, then your speaker is probably messed up.
You should get a reading of around 4 ohm, give or take 1 or 2.

 

Also, have you had your cruise control recall done? If so maybe you poped the fuse.
If not, maybe its a sign.
