Title: headlight/wiper switch replacement
Post by: jim on July 07, 2011, 09:13:09 PM
If someone will be so kind as to post again what is actually required to get to the switches I'll appreciate it.  It seems to me that the TSM would have me remove more than what is really necessary to replace the switches.
Assitance appreciated.

Thanks, Smitch.  That'll be helpful. 
Now I need to know how to access the headlight switch.  The instructions I find explain how to completely remove the instrument panel and gauges. 
I thought someone explained how to tilt something out to reach the switch.

I think you may be able to get your hand up in there to push the button and remove the handle. Remove the retaining nut, then try to wiggle the thing down to a workable place to remove the wiring connectors.

Someone also suggested that you can remove the 2WD-4WD switch and get you hand up in there to at least remove the wiper switch.  Not sure if you can reach all the way up there for the headlight switch.  If you just remove the screws around the main dash panel, you'll be able to tilt it forward and remove the switches, without removing the instrument cluster.  Good luck!

vangremlin, I think that's the hint I was thinking about.  Just wanted a refresher before I tackle it.  Thanks.

If you can do a write up when you're done that we can archive in the Eaglepedia, Jim, it would be appreciated.

So far I don't have anything to write about.  I haven't been able to get the panel to tilt out.  I did find out that I can reach the wiper switch through the 4x4 switch hole.  More about that switch later.  I think I can reach the headlight switch through the same opening but - I can't get the @#^%^headlight knob off!  The shaft has ridges to hold the knob, and mine looks like it make also have some glue on it. 
I tried holding the shaft with pliers and trying to force the knob off with another set of pliers, but it hasn't worked.
How can I get the headlight switch knob off without breaking the plastic dash?

The knob and shaft are "one piece". When you pull the knob out as far as you can, then push the button on the switch it should pull the rest of the way out.

Yes, there is a button on the switch itself, behind the dash, that you have to push and then you will be able to pull the knob and shaft the rest of the way out.

So I discovered.  Project complete.  I'm working on a write up, but it's too late tonight to finish.

I was going to replace the wiper switch because I thought the shaft was so worn the knob would not stay in place.  I discovered that the inner part of a knob was pushed onto the shaft preventing another knob from going on far enough to latch.  That problem is resolved.

I was going to replace the headlight switch because I have no high beams.  The replacement switch functioned exactly as the original and I still have no high beams.  The switches are slightly different so I replaced the original switch.  Onward with troubleshooting.  I suppose the next place to look is in the steering column.

You could check for power at the lights on the off chance that both bulbs blew at the same time.

I have swapped out lights with the other Eagle and back again.

This can be moved to the Eaglepedia, but I suggest waiting for a few days.  Someone may have comments or even corrections! :o

The wiper switch and headlight switch can be replaced by reaching up through the opening for the 4 wheel drive selector switch housing. This may be very difficult for those with large hands.

Disconnect the battery negative ground cable.

Remove the 4 wheel drive selector switch housing by loosening the two screws securing it to the dash.  The screws do not have to be removed completely.  If they are removed completely, replace them leaving them very loose before reattaching the housing.  Nothing inside the housing must be removed.  This housing is held in place with a metal plate that fits inside the opening.  It will come out with the housing.



Remove the wiper switch knob using a small screwdriver from underneath the shaft to press upward.   This has been discussed elsewhere.



Again using a small screwdriver, remove the lock nut securing the switch to the dash.

Reach through the opening in the dash and carefully work the wiper switch out through the opening.  It is a close fit but it can be done.  Unplug the connector and ground wire, hoping and praying that the other end of the ground wire is securely fastened within the dim reaches somewhere under the dash. (http://img.photobucket.com/albums/v416/jimmiesmith/wiper_headlight%20switches/IMG_1273.jpg)




The headlight switch knob does not have to be removed.  The shaft can be released by pressing in on a button on the side of the switch.  The button is on the side opposite the connector.  Reaching through the opening, press inward on the button on the side of the headlight switch, and pull out the shaft. 
(http://img.photobucket.com/albums/v416/jimmiesmith/wiper_headlight%20switches/IMG_1277.jpg)



With a screwdriver, remove the lock tube and remove the switch.  The switch can be worked out through the opening but it may be easier to first unplug the connector.  Unplug the ground wire on the back of the switch.  We again hope and pray that the other end of the ground wire is securely fastened.  The connector has keepers on both sides that must be opened.
(http://img.photobucket.com/albums/v416/jimmiesmith/wiper_headlight%20switches/IMG_1274.jpg)


This is the spade connector for the ground.
(http://img.photobucket.com/albums/v416/jimmiesmith/wiper_headlight%20switches/IMG_1276.jpg)



To replace the switch, connect the plug and ground wire and carefully work it in through the opening.  With a screwdriver, replace the lock tube.  Insert the shaft.  You can feel it click into place.  Pull on the shaft to ensure that it is in place.  Reconnect the battery cable and test the switch.  If it works correctly, disconnect the battery cable.

Insert the wiper switch through the opening and connect the plug and ground wire.  Insert the switch through the opening.  Replace the lock nut with a screwdriver and install a knob.  Connect the battery cable and test the switch.  If it works correctly, the battery cable may remain connected if your battery can hold a charge with the doors open as you continue working.

Replace the 4 wheel drive selector switch housing.

Thanks Jim. I'll bookmark this for now and enter it in a couple days.

Removing the dash part ot get to the switches is made to sound a lot easier than it is.  Unless you have monkey paws with gorilla grip forget about reaching up through the 4wd opening or under the dash to release or remove anything.

What do you suggest?

I suppose I have monkey paws or gorilla grip because I removed both switches through the 4wd opening.

Are you sure you didn't cut a hole through your firewall?  ;D
When I changed mine a few years back I don't recall any major difficulties either.

The hole in the firewall option was looking tempting before I gave up on tilting out the instrument panel bezel.
Luckily I don't have large hands.

The hardest "up under the dash" problem I've had so far was finding the flasher for the signal lights. It was higher than the light switch and closer to the windshield. I didn't put it back up there after I changed the flasher. Did you have to change yours when you added trailer lights?

My cluster wouldn't tilt forward unless I was able to get the electrical connections and speedo cable loose.  I could not get a hand up behind the cluster from below or from the 4wd opening.  I could see up there but no way was there enough clear space to reach up.  I had to remove some additional screws that held the front part of the cluster to the rear part in order to finally get the thing out without breaking anything.  Even then I was only able to get it out far enough to get to the headlight switch and replace it.  Turns out that wasn't the problem after all and all that effort was no more than an exercise of experience.  Maybe some are put together with some extra wire or tabs have already been broken by previous owners but even reading the removal instructions word for word which are here on this site, the removal was not in any way as easy or worked as described for me.

Yes.  I went with a heavy duty flasher.

As I mentioned, my headlight switch wasn't my problem, either, so I too did it for the experience.  I gave up on the dash removal.
