Auto door locks

(1999 Mercury Sable)
when I turn the key on to start the car the door lock's will lock and unlock for 30 to 45 seconds over and over again. I try to engage the door locks to lock or unlock the driver's door does not work and I have to manually lock the door. All the locks are working but not in unison. Be sure and take key out of ignition before shutting doors because then ALL the doors will lock!!!!
What do I have to do to fix this problem???? Also dash lights will not come on when I start the car but will light up when I turn on the head lights???

2002 Mountaineer has this problem, here are some of the answers. Try it, only cost a can of wd40. I tried it on mine, so far so good.
with all the doors closed and locked, the door ajar indicator is on. Often while driving the locks will unlock and relock.
Took it to the dealer and paid $100 for them to put oil on the locks and they started working again. So try oiling the locks before you waste money like me
We have a 2003 Merc Mountaineer which had the "door ajar" indicator and courtesy lights would not turn off after parked. Read your articles, went out to garage, sprayed all 6 locks (4 doors, rear window and rear hatch)and then opened and shut each about 10 times. Lights went off in about 25 seconds and no more "ajar"!

I have not received a answer to my question as of yet. Talked to a mech at a repair shop and the cost of having him to check and repair would run from $125.00 to $ 375.00 to repair or replace parts. No answer on the dash lights!!!!!!!!
