I have a 2002 ford ranger edge 3.0 non flex fuel, and I have a few problems....First my electric door lock don't work as well as they use to.They work with the keyless remote, but barely sometimes I have to hit it a few times, it seems like the motor for the locks is weak, when inside the truck using the switches it will lock but will not unlock. The mirrors don't work at all anymore, it used to work a little but gradually got worse, some one told to me to use wd-40 but it didn't work I'm thinking it could be the switch, BTW i've checked all fuses. Also My brakes seem like they are pulsating when I stop. Sometimes it feels like I have oval wheels, it will also pull to the right only when braking. And I hear kind of a ticking sound in the engine...Loose rocker, or burt valve? when accelerating it sounds more like a jingling of change, but very faint, but its only when accelerating, also sometimes iwhen idleing it will shake a little, but not much or very often....just wondering what it all could be.

 

It's a sad shame that nobody answered this thread. Oddly enough my 2000 does the same damn things! My mirrors still sort of work though, but my locks rarely unlock and lock without the use of the key, when I first got it the key wouldn't unlock the driver's side! The back doors wouldn't stay shut, but with some beating and rust eating stuff it worked a little better. I also have that obnoxious jingling sound and sometimes it shakes a bit while idling... I removed the front "skid plate" today to see if it gets any quieter. It was buzzing and clanging every time the door was shut, hit a bump, and at certain RPMs it would resonate.

If I find the jingling, or the cause of the intermittent missing, I will post it. Good luck to you.

WD-40 worked a little on the locks, but I think it needs more!

 

I applaud you for using the search function good sir.
Your mirrors not moving could be a mirror itself issue. My passenger mirror dosen't work in the up or down directions, but left and right works fine. opposite for the drivers mirror.
Your locks not locking could be the Actuator itself has gone bad, If one switch or the other opens it better than the key, i'd say its an actuator.
The obnoxious jingling is something thats hard to diagnose without hearing it. you say it resonates when you hit a bump? the fits thing to check could be your sway bar links.
Are you 4x4 or not?

 

Thanks for replying, I've been searching for quite a while, lots of people have the problems and nobody seems to know what it is... I took a short video of the obnoxious sound.
Yes, 4x4 off road. On my profile in the About Me explains my truck, I didn't want a huge signature with every post :)
http://youtu.be/VCEVUk8kLPs << you can hear grindy noise.

 

I tried to add a signature... hmm no worky.

anywho, the front "skid plate" was what was resonating at certain speeds and "chattering" on bumps. I'm thinking of coating the inside of the "skid plate" with a rubberized paint, maybe... or rubber washers, maybe both.

already fixed mirrors, I think. driver's lock actuator works most of the time... passenger side probably needs replaced.

 

Check your pulley's and bearings.

 

coming from rear of engine... will make same noise in Park at same rpm. guess I need a helper to sit in truck and give it gas while I'm under it. thought it was an exhaust shield, but it's tight. idk.

 

I hooked some baling wire around the throttle and ran it down under the truck so I could be under there and idle up... that horrible noise is either in the bottom of the engine or the front of the transmission (auto). I'm going to need a better stereo, cuz it annoys the hell out of me.

 

Might just want to take it to a Mechanic. he should be able to tell you what it is.

 

He'll say IT is $200 for the diagnostic, it needs a rebuild of the engine and transmission! heh couldn't help myself

 

Then tell him to stuff it.

 

I'll just drive it until it stops making that noise... it will either remedy or reveal itself :)

 

my dad grew up with tim wakefield and he would always say if you cant find it, dont fix it. they used to lower of VW bugs but it applies to rangers as well i guess

 

if it ain't broke don't fix it! I'm guessing yours doesn't do this?

 

Well my passenger actuator for the door pin sucks a [ 8===D ], but you learn to fiddle with it, I lost my beeper thing a long time ago (felt a bit girly using it), and my mirror motors only work in a certain directions as well. but after 11 solid years and 180,000 later you realize parts break. So thats why you fix them.

my seat belts dont roll up, radio bezel doesnt sit right, wax melted off my cruise control pods, rattle in my dash, battery intermittently likes to drain itself, computer auto resets randomly, have scuff marks on door panel from boots, carpet is stained and eroded from battery acid, **** happens

and i dont have a skid plate, but im building one lol

 

wow, I feel lucky with only a few quirks left to fix!

 

your brakes.... need to be replaced, the pads that is, and rotors, they are warped, which is the pulsating. im guessing your pads are spent from the warped rotors. and as for the engine noise, it's prolly in your bell housing. if you feel like looking in there. maybe a bolt or somethng that has come loose. the mirrors and locks, check the relays, and replace the fuses anyway, i mean its only $5.99 for a good fuse set.
