Power mirrors not working, I may be missing something?

FC Zach · May 21, 2013

I searched "mirror switch" and "No suitable matches were found."

I've had my armrest/ center console out and checked possible wiring problems, and I found that I have a connector pigtail not going to anything. I have my car together now and figured I would ask here before pulling the armrest off again. . .

While searching the web I found this on FleaBay, this is actually a switch and relay assembly for the JDM power folding mirrors but I was wondering if my unused pigtail is for a relay that I don't have and possibly the reason my mirrors don't work. Any ideas??

I guess what I'm asking is. . . even though my car didn't come with the power folding mirrors, should there still be some sort of relay by the switch?

FC Zach · May 28, 2013

I believe a previous owner may have installed power folding mirrors but not entirely sure, I'm still trying to diagnose my non-functioning mirror issue and while searching for a relay like the one above I found a set of mirrors on ebay. I checked the numbers on my mirrors and the numbers match, here is the pic from the listing. Do these numbers indicate the model of mirror you have or are these numbers the same on all Celicas?

If these are the folding units then there may be a whole mess of problems as to why my mirror adjusting switch doesn't do anything. I guess I'll be needing a writeup on how to make the JDM mirrors work on my USDM 92.

It does look like you have a set of folding mirrors. There are a few write ups on the internet about wiring up the folding mirrors on a USDM chassis.

FC Zach · May 30, 2013

Thanks, I've seen a write up before just don't remember where.

Here's a new one, looks like it'll be a big help. http://www.alltrac.net/phpBB2/viewtopic.php?f=22&t=9612

I normally pre-wire everything and give it to the buyer all hooked up.

I have noted other wiring colours if your's don't match the wiring code on the link that has been provided.

What 'pigtail' isn't hooked up? Not sure what you mean by 'pigtail'

FC Zach · May 30, 2013

The other pigtail/connector I mentioned that isn't going to anything may be for the power seat that a previous owner had removed. I just assumed that it could be for the mirrors since they didn't function.

count the number of wires in the connector loom and list out the wire colours.
Easiest way to determine whether they are for the mirrors or not.

Easiest way to to use your own wiring to make it work.

FC Zach · May 30, 2013

Will do, thanks for the help! I'll do this when I get off work.

deecee · May 30, 2013

just to check, do you have the control, relay box and the mirrors? If you are missing the relay box, then the setup isn't going to work. The relay box is located underneath the drivers side panel next to the steering column on RHD cars.

If you really wish to solve, then you need to trace the wires through the loom and see where they end up.

Unfortunately, its a bit hard to ascertain what modifications your car has without being there and taking the car apart..

FC Zach · May 30, 2013

Not sure if I have the relay or not but I will check for that too. I have a LHD car and I would presume that it's still by the column? I'll sort this out when I get home, thanks!

The vacant connector I mentioned earlier that I now believe may be for the power seat is a 9 pin connector with only 6 wires. Colors: red, white/black, white/blue, black/blue, black and red/blue.

FC Zach · May 30, 2013

Here's a pic of the connector and also a pic of a retractor control. The numbers on the retractor control don't match up to the pic from Ebay above, is the piece for headlights?

FC Zach · May 30, 2013

This retractor controller box mounted by my fuse box.

FC Zach · May 30, 2013

Well here's my problem, maybe these wires need to be connected to something lol :bangshead:

FC Zach · Jun 1, 2013

I've connected the three wires necessary to make the mirrors function. Now to study the write ups to learn how to wire up the folding option.

FC Zach · Jun 19, 2013

Now that I've learned a previous owner had mounted power folding mirrors on my USDM car at one point in time and that they were never wired (not even the three wires for the mirror adjustment on each side) I have decided to complete what was started. I purchased the switch & relay box pictured in the original post. The parts came in the mail and I have already studied the wiring diagrams from other members who have successfully adapted these mirrors to function on a USDM ST185, one like this:

It all seems easy enough. I'm gonna run the four extra wires to each mirror but I would like to know where to properly mount the mirror control relay on my USDM 1992. Member DeeCee responded in an earlier post that "The relay box is located underneath the drivers side panel next to the steering column on RHD cars.", what about a LHD Celica? If there isn't a proper place to secure it I guess I could just mount it anywhere like under the radio.

deecee · Jun 19, 2013

Securely mount the relay box in an under dash location where it will not get knocked around - don't be tied to doing things in a perfect OEM way - be practical and logical

FC Zach · Jun 19, 2013

Done, zip tied down to cruise relay?
