The doorlock seems like they don't have enough power to lock or unlock the doors even when I use the keyless entry. So when I put my alarm in I hooked the keyless entry that the alarm has and it does the same thing. You can hear the acuators tring to work. I thought it might be the relays. If it was the relays it wouldn't do anything right? Any idea's

 

are they both doing it?

 

yea both

 

how bout we get some specs on your truck...

that would make a much more appropriate sig instead of "word", Homes

 

99 3.0 4 door step side auto 2wd

 

I have a solution. new accuators new wire, new relay's and new switches.
well try taking off your door panel and finding where your accuators plug is. then run a pos & neg from your bat. and put them on the plug or the accuator. then ir the work fine then it is somthing diffrent that i dont know about!

 

Itz the actuators my 2000 did it too. Buy em online for 80 bucks and get em in. Itz a lil difficult but I figured it out. So if you have any questions I can help.

 

Where exactly can these be bought from for the best price? I just checked Autozone and they want $44 each.

Ive got a 99 Ranger supercab with the 3.0 Flex Fuel, and Im having the same exact problem.

 

Go to a car audio place, they charged me 15 bucks each when I did mine.

 

Did you add power locks or replace the factory acuators. I would think the factory ones would be a lil more expensive than 15 bucks. 44 each sounds to be about what I paid for them.
