After repairing the blower motor, the central locks have now stopes working. When I look in the center counsel area there are a couple of wires mysteriously not connected. I'm sure this is the problem, but I can't tell where they reattach, if to anything. When I lift up on the drivers side door lock I hear a clicking noise from the relay, but the locks don't all go up. I'm wondering what the probable cause might be.

I've been finding lately that my driver's door lock cylinder doesn't always return to neutral. Sometimes it stays in the lock or unlock position. Make sure the door's lock cylinder is not turned either way by turning it until the locks lock, then back until they twitch a little.

Then give it a shot. It might be that simple.

Good Luck

Knowledge is knowing a tomato is a fruit; Wisdom is not putting it in a fruit salad.

When I lift up on the drivers side door lock I hear a clicking noise from the relay, but the locks don't all go up.

If you can be real specific about the symptoms -- details please -- we can probably get you closer to the trouble. Unlock/lock, key switch, which doors, etc.

A skeptical anthropologist was cataloging South American folk remedies with the assistance of a tribal Brujo who indicated that the leaves of a particular fern were a sure cure for any case of constipation. When the anthropologist expressed his doubts, the Brujo looked him in the eye and said, "Let me tell you, with fronds like these, you don't need enemas."

pulling up on the front driver's side door usually open up all the door locks. pushing it past locking would close them all. i don't recall trying the locking function, but the unlock feature doesn't engage. With the center dash apart, and while "testing" that unlock feature, i could hear a faint clicking. In feeling around for that noise, i concluded it was coming from a relay right under the center air vent. like it wanted to engage, but just couldn't trigger something more.
i'm not sure how to explain it anymore than that. i don't know where any other parts of the central locking system would be, just really wondering if it could be a relay or something. but then again, every time i think something is broken... A little "spring cleaning" inside the mess-o-dash wires, and i seem to get a few things back.
two projects forward.. one project back.

Now, or before the blower motor repair?

i don't recall trying the locking function, but the unlock feature doesn't engage.

Can you try it again so you don't have to rely on recall?

The relays are above your heater. They get power from fuse 8 and ground from a black wire in that mess of grounds at console upper right. The paired blue and yellow wires go to the actuator motors in three doors and the tailgate. The switch wires come in from the driver's door in red and green -- red gets grounded for lock and green for unlock. If you heard clicking but no action at the doors, maybe a relay or two have pulled slightly loose from their sockets just below the center vents. Look for two relays with red, green, black, blue, yellow wiring.

Wear short sleeves! Support your right to bare arms!

that sounds more like it. thanks. Yes, everything was working fine before the blower motor transplant. The locking function doesn't work..
I believe in haste, everything taken apart for blower motor access was put together just sloppy and too fast. Now I have to see how much backtracking will be needed to correct everything. i was dreading those supports near the center vents and then the steering column stuff... seems like the job has to be done again, just to get it right. I'll check those relays and find where the rouge wires go to.... i'm not really thinking any wires should be loose in that center counsel mess. but i saw a couple.
Now i don't have a hazzard light.. still have hazards but that little bulb inside the switch doesn't want to light up. I know i have to get all the wires where they should be, but i've got to look at schematics to see the general route of things. easier said than done i guess

So, there's these two green wires in the center dash area. both of them with the bullet?.. style connectors. one, from experimentation i know goes to the glove box. the other, i'm almost assuming goes to the flasher relay. I'm not 100% sure though. the schematics say all of these green wires should go to the same wire on the same fuse and seem to be constant.. what gives?

Check the black ground wires that have to be secured to the metal frame of the center console. One may be involved with door locks.
