I have an 89 f250 7.3. horn has not been working for the longest time the relay clicks but still nothing. It doesn't matter weather the key is in the on or off position. I know it might be a grounding problem because the cruise control does not work any more (even though recently it was working just fine). I didn't see any bad fuses.
View 6 RepliesI am trying to find out if Ford's cruise control has gotten crappy, or if mine has problems in my '06 F250. When I set the cruise, it goes about 3 MPH above what I set it at, then drops to about 3 MPH below, then it eventually stays where I set it. That is until I come to the top of an overpass or other small grade, then it is back to about 3 MPH over again as I reach the top and level out, then going back to where I set it.
The cruise control in my previous Ford trucks (83 & 91), as well as my 82 Mustang, 85 Lincoln, wife's 97 Toyota and the 2013 Chevy rental I just had, works fine. Where you set it is where it stays. Of course going up or down a steep grade, they all are going to lose or gain speed.
Anyway, I have taken the truck to the dealer twice for the cruise control. The first time is when I got the truck in '08. They replaced something else non-related, and said that would fix the cruise. It did work marginally, as the fluctuation was +-4 MPH before. I just took it in again before it goes off warranty, and they said the cruise is operating normally. So, there's my story. Is this normal, or is something wrong?
F250 6.8L .. So Ive read a lot of posts about intermittent cruise control issues. I understand that the most common failure is the brake switch on the master cylinder. My concern is that I am unable to run the cruise control self test I keep reading about. Does this test not work on my model year. I have tried even when the cruise control is working and still the cc light does no come on.
View 2 RepliesI have a 1994 f150 5.0 engine and automatic transmission. Problem I am having is speedometer, cruise control is not working. Overdrive light is flashing and number 18 fuse keep blowing. horn is still working...
View 1 Replies1997 F250 HD 7.3L It is a May build so is mainly 1996 parts. Came from the factory with auto transmission but PO did manual swap. Truck had factory cruise control but never worked after the swap. I found clutch safety switch missing so installed that and now it works as far as truck only starting with clutch in and other pins ohm good but it didn't fix the no cruise issue. All the diagrams I can find are wrong so I am stumped.
Horn works and steering wheel brushes appear to be functional.
Brake switch has 12V in and out so I think it is ok.
Brake switch on master cylinder has power in and out so I believe it is ok.
All brake lights work since I read that diagrams don't show it but they are somehow tied into the cruise.
I believe the issue is in the clutch safety switch (CPPS) wiring as I only have power on one wire however my colors don't match my Haynes or online diagrams. Also, no where can I find if this circuit runs on hot 12V or ground. Some wrong diagrams show hot 12V coming in on the light green wire from the brake switch but others show a hard ground on the red/Blu wire.
Most diagrams say I should have red/LtBlu, Red/LtGrn, LtGrn, Gray/Yellow. I actually have Red/Blue, White/Red, Tan/Blue, White/Brn. The White/Brn has power coming into the switch.
The connector for the automatic transmission column shifter is disconnected and the shifter was removed. I read that this needed to be jumpered to the tan/blue wire after a conversion on the CPPS but only on 2002 and up trucks so I don't think this affects me. That plug is for overdrive cancel.
Looking for a good diagram for a manual shift, diesel cruise control circuit that shows my color wires on the CPPS? I have had this truck 2 months and have fixed everything except this and will be making a long trip soon so cruise would be nice to have functional but I am stumped.
1991 F250 Supercab Diesel 4X4. I made a mistake while wiring up my trailer lights and ended up grounding out my brake controller, frying it. Along with that, I popped a couple fuses as well (1, 5 and 9 I believe). Replaced all fuses and got my signals (F/R) back at least.
Here's what's NOT working/messed up:
*Brake Lights
*Cruise Control
*Rear ABS light comes on a few minutes after driving.
*Front hazards work, not rear. When I apply the brake, the hazards pause in the on position.
I've tested the brake switch on the brake pedal (Green/Red and Green) and it works properly. So, current is obviously not reaching the rear brake lights.
Another note. The truck is wired with a 7 pin plug in the bed for a goose neck trailer. It also was wired to a 6 pin on the bumper. I replaced the 6 pin with a 7. The signal/brake pins on the plugs (both) and also not receiving power. What's the next thing to check?
I have a 2001 F250 with 7.3. We swapped the auto for a zf6 manual. We left the auto's shift position sensor tied to the frame and left in neutral. I did install a pcm from a manual transmission pickup. Also have the clutch position switch hooked up. I have an Edge Evolution CTS2 reprogrammer, and on the display the gear indication always shows P. I suspect that is why my cruise doesn't work. For interests sake, I tried manually adjusting the shift position sensor through all gears, and the reverse lights come on when in reverse but the Edge's display always shows P. My question is with a manual transmission, how does the pcm know that it is in gear? The only sensor that I am aware of is the reverse sensor on the zf6.
View 4 RepliesLooking for wiring diagram for the older Ford cruise control switches. I'm wanting to add an aftermarket system but use the factory switches. It's for a 99 ranger with the steering wheels like the mark 8s, older mustangs, explorers, and many others, had.
View 1 Repliesi have a 96 ranger and want to put cruise control in it. is the wiring there and what other parts do i need to get without going aftermarket.
View 1 RepliesI have a wire that i think belongs to my Cruise control and I can't find out were it connects. It is dark blue/green stripe. It is in a wiring bundle with the oil sending wires ( two wires blk/w and y/o ).
I also get a code ....no sig from clutch neutral switch.
I just got done putting new heads on my little 2.9 and can't wait to use this as my daily drive. These two wiring issues are keeping my truck from running well enough to drive.
Where is the cruise control amplifier located on an 85 F-150? The Chilton manual just says "behind the instrument panel". No pic or further description. Just looking up from the bottom of the dash I see a "black box" with 2 wires going into the top of it located just between the steering column and the wiper switch.
Is this it?
Many of you said it was the "ClockSpring" that needed to be replaced. But I already did that. A brand new clockspring on it. The horn only blows when the engine is off and when the engine is on the horn and Curse Control don't work. I have a 2001 Excursion. So What could the problem be? It works with the keyless remote. But just when you driving down the street and some bone head cut you off you can't just it.
View 5 RepliesI recently changed out the power boost canister for the brakes on a 1990 f-150 2wd. It was successful but now i have no cruise control. I double checked my plugs, all good. I checked my brake lights, all good. brake pedal seems fine and completely raised when not in use. i looked for a fuse and can't find it for that system, seems odd. it's not in fuse jct under dash, can't find a fuse jct under hood, seems odd also. No check engine light has lit.
View 3 RepliesI have an '02 F150 Lariat CC 5.4L. The truck is new to me and neither the cruise control nor the horn works. i have checked all (known) fuses and relays. I have tried the cc diagnostic, and the dash light DOES NOT illuminate. Should I assume that the dash light is not burned out? Is there a way to test the clock spring connections for continuity? and how do I access the connection
i checked the cc brake pressure switch and have continuity there.
I have a 2005 Excursion 6.0 ... .. A few months back the horn started sounding on its' own in the night, so I pulled the fuse... .. Then the Cruise Control stopped working. I have googled references to clockspring failure and these problems... ..
View 3 RepliesI have a 2001 F-250 SD XLT with the ABS light on, cruise control doesnt work and the horn only works with the key out. The codes for the ABS is no signal input from the left and right front wheel sensors. No problem there. Also my speedo stops or jumps when I press the horn button while driving down the road. When I quit pressing the horn button the speedo works fine. So after looking over the posts on cruise control, etc. Does the rear speed sensor have anything to do with the cruise, horn not working? All fuses are good so I am thinking the cruise control switch on the master cylinder or a short in the steering wheel column or my ignition switch. What do you all think?
View 7 RepliesI am having trouble with all sorts of functions on my 2002 F150 4x4, 4wd not working, cluster module illumination not working, horn not working, reving up and down at idle and sometimes dyin, cruise control quit working. I have been reading it is the GEM module that causes these issues. My question is I ordered a new one from Ford, when it arrives I was told I can just install it and It should be pre programmed. but one ford house tells me that they have to install it and program it. Which it right? I have seen several sites on u tube where people replace the module and then start their truck right up without any issue.
View 2 RepliesWell I've had her just 1 week, used, and today I turned it on and the power is out on the A/C n Heater /Fan Control ASSY. It worked the last 900 miles from FL to OH. And today worked this morning, but 2nd time I got in the truck today there was No Lights in the Air Control Assy. I didn't get an Owners Manual, so what fuse to check.
View 3 RepliesI have a new to me 2008 F250 XLT. Neither side on the power mirrors is working. The manual shows fuse number twelve on the passenger side fuse block is the one that controls this circuit. The fuse is good (continuity wise). What I need to know is what color is the wire that feeds power to the switch block on the driver's side door panel. Pulled it out of the door panel and wiring was intact and corrosion free. I need to find out if there is power there or is it an issue between the fuse block and the switch.
View 2 RepliesI have an early 99 F250. The a/c compressor stopped working. Have checked pressures, switches, freon etc. Found the switch in the dash is not getting power to send to the compressor. Where the feed for this switch is? I have checked all fuses, all good. The manual does not show a relay as being an a/c relay, so I am stumped without taking it somewhere now but I would like to avoid that.
View 7 Replies89' Bronco 5.0 EFI. My Bronc has no power at all! Heres the senerio... Parked it this past Thursday night 2/16. Tried to start it Friday morning 2/17. Starter just acted like the battery was bad. Took the battery to 2 different auto stores to have it tested and it passed. Initially the starter just tried to turn, after I put the battery back in the solenoid just clicked, no starter. I already replaced the starter and starter solenoid on Monday 2/13 with a new, not reman starter.
At this point I am just throwing parts at it. This past weekend I replaced the ignition tumbler, the ignition switch on the column and today I replaced the EEC relay. When I check voltage to the stater solenoid I get voltage to both sides??? I also get voltage from the red ignition wire to the top of the solenoid. Otherwise have zero power to the rest of the truck. No radio, no dome lights, no headlights, power locks, power windows or back glass. What gives?
