Cruise Control Troubles March 22, 2014, 07:45:04 pm Yahoo Message Number: 145437After 5 1/2 years of full timing, three days ago, my cruise control decided it was not going to help me as I drove from New Mexico to California. Everything pointed to an absence of electrical power to the cruise control system. My first night, I pulled the Ford owner's manual to find and check the fuse. I found no reference to cruise or speed control in the listing of fuse uses.I called the Ford assistance number and talked with a tech person. He told me they supply the chassis but they do not fully wire the fuse panel, leaving that for the RV manufacturer. He suggested I check the fuses with a meter. I pulled out my voltmeter and checked both sides of all the fuses I could get to. All showed nominal 12 volts on both sides, suggesting that the fuses were fine.The next morning, I called Vince. His reaction to Ford's answer was a mix of astonishment, indignation and irritation. He said the cruise control system is not touched by LD, that it comes fully wired and fused, but he did not know what fuse applied. He referred me to a Ford truck service facility. They told me the fuse was number 11 under the dash.Meanwhile, I had asked for, and gotten a number of suggestions from friends on this forum and elsewhere. All seemed to point to a fuse problem.Yesterday, a young lady with a much smaller frame and hands than I have offered her help. She crawled under the dash and pulled fuse #11. I checked it. It tested as good. She put the fuse back, and I resigned myself to an expensive repair in the future.This morning, I resumed my journey. When I reached the highway, on an impulse I tried the cruise control again, and it came on. It ran, trouble free, all day, including a break for lunch and re-start.I now figure the most likely issue was dirt or corrosion on the fuse panel contacts which was cleaned when the fuse was pulled and replaced.SO - if any of you have a model year near mine (2008) and have a problem with your cruise control, I suggest that you pull and re-insert fuse #11. It worked for me.

Re: Cruise Control Troubles Reply #2 – March 24, 2014, 04:41:04 pm Yahoo Message Number: 145456Your problem has been reported before and we have the same problem in our 2006 but it probably isn't a fuse. Ed Daniels used to own a 2008 and had similar problems. Our problem is that the cruise would work then cut off and sometimes would not turn back on. There was no way to predict when it would happen. Sometimes it wouldn't start from the first try or it might start working later on as your driving.The solution that Ed found turns out to be something called the brake pressure switch and it is attached to the bottom of the brake fluid reservoir. I haven't replaced mine yet since it is working more often than not.Jim C
Re: Cruise Control Troubles Reply #3 – March 25, 2014, 11:18:53 pm Yahoo Message Number: 145479Yeah, me too. Yeah Yeah, me too, same situation, same fix (sort of) and problem gone. I was using the cruise until I turned it off as I approached a rest stop. Rest stop behind me, tried to engage cruise to no avail. At very next rest stop did an engine shut down, rested, and resumed trip. This time cruise engaged as it should and I haven't had a problem since. No fuses pulled. Go figure!Steve S.

Re: Cruise Control Troubles Reply #4 – March 26, 2014, 11:01:26 am Yahoo Message Number: 145484Steve, following up, me too. The day after the fuse was pulled I had no issues - the cruise control was fine. The second day after it was pulled, when I started, no cruise control. Thirty miles later I stopped and filled with gas, and when I continued my trip the cruise control was back. Over the course of that day, it never cut out while in use, but there were two times where it was "on" but not controlling speed for a while, then it would not resume control, yet later, with no interruption of the trip, I was able to re-engage the cruise control by pressing "On" and "Set". It clearly is an intermittent issue. I will have a pro deal with it in a month.Ken F now in southern CA
Re: Cruise Control Troubles Reply #5 – March 26, 2014, 09:24:50 pm Yahoo Message Number: 145489Hello Ken: Jim C. diagnosed the most likely cause of the problem in his response to this thread: "Your problem has been reported before and we have the same problem in our 2006 but it probably isn't a fuse. Ed Daniels used to own a 2008 and had similar problems. Our problem is that the cruise would work then cut off and sometimes would not turn back on. There was no way to predict when it would happen.

I haven't replaced mine yet since it is working more often than not." It cost me $200 of electronic diagnosis/trouble shooting before the garage came to this conclusion. A $25 brake pressure switch remedied the exact intermittent cruise control issue you are now experiencing, in my '08. The function of the brake pressure switch is to deactivate the cruise control when you tap the brake peddle. It's a do-it-yourself fix or tell the garage to just humor you and replace the part. Or pay them to diagnose the problem and then replace the part. ;-)Enjoy your travels, Ken.Ed
