Question Memory mirror question

I have recently just aquired a set of LHS folding memory/heated mirrors(thanks Terry..Wolfspirit).

Well what a job..all the wiring, door removal, etc.

After completion I have hit a snag, and am trying to figure out the cause.


The driver mirror memory doesn't function. No tilt in reverse no nothing.(use of the original mirror switches are fine)
Interesting enough the passenger mirror memory does function, and seems to properly, with the exception of the tilt down in reverse.

The passenger mirror does tilt down in reverse, but it doesn't return the original setting.


Here are my questions.

1. is the driver mirror supposed to tilt down in reverse?

2. are the mirrors supposed to return original position after you put it in gear? (tilt in reverse)

3. Do I have a bad memory module, or a bad mirror module?

Any help greatly apprecieted.

Even w/o all the memory stuff, these mirrors still look 100 times better, and they are heated. (still waiting to see if that works.)

Well I now have fully functoning memory mirrors!!

Somehow the driver mirror had lost the 5 volt sensor input, after I fixed that I now have full memory.

The tilt in reverse is still iffy, it does tilt down on both mirrors, but they do not return to their original postion, minor annoyance anyway.

And the heat works awesome, I can't believe DCX chinced out on that, even the 1st gen trep had it.

Odd - I also thought the mirrors would return to their previous position ... :-/

First off, none of the functions will work properly without the 300M/LHS memory seat module. All of the functions are governed by it.
As well, the tilt in reverse feature is only useable if you have an EVIC as well as the HSMM, since it controls that function's "on-off"
You don't say if you have the heated memory seats.
The other issue, is that - hopefully - you wired the heated circuits to the rear window defogger relay & fuse.
Factory-wise, that is how it is done, so as to supply the correct voltage as well as thermally protect them, and also so that they turn on and off with the rear defroster switch and the ignition over-ride.
If you wired them to a direct 12 volts, you will potentially fry them very quickly.

Well I have all the functions (up, down, side to side and heat) working but the memory still doesn't work. It doesn't bother me much as I'm the only person driving the car anyway.

Yes I have the HSMM in my car, I had acqiured some pro-am seats but they looked like crap in my car,( and I didn't have the rear seat to boot) so I took the module and the seat track and installed in my trep. I put the memory set switch where the trac control button would have been.

And yes I have a fully functional EVIC + PSI

And yes I did wire the heat to the rear window relay, grabbed the 10amp fuse holder out of an M in the bone yard.

I have everything in place, everthing works perfect, except the tilt in reverse.

It tilts down, but doesn't return when switch gears.

Everything else works, the seat is perfect, the radio presets change with the memory, the mirrors work with memory.

Its just that damn tilt in reverse! LOL Not a big deal but, it would be nice if worked right.

I am assuming that the HSMM may have a defect, but I am not sure.

OK, so, since you have all of that, the first place to look is the actual mirror it self, since only 2001 non-signal mirrors and 2002 mirrors (both) are the only ones with the right side tilt feature.
Also, assuming that you have both mirrors with memory features - 10 pin plugs & all the wiring in place except for the signal wiring of course, what year did the seats come from. 2001 & 2 and a very few early 2003 HSMM are the only ones with the right side tilt & memory feature. After that it was deleted, which could be your problem, in conjunction with the possibility you have the right and left side wiring reversed, which would explain why the RIGHT mirror memory & tilt works (somewhat) and the left doesn't work at all.

I'd be inclined to first double check that you have, in fact, wired the sides correctly to the HSMM, then check the year on the module. I'm pretty sure there is a build date on them, if not, I can let you know the part number that is the only one with the 2 sides operable.

See what happens & report back.I have a couple of mirror modules & seat modules, so if it comes to that, we can see.

Thanks for the info TFC!!

My HSMM is from an 02 MY

The mirrors I am not 100% sure on. I do know they are from an LHS


Both of my mirrors function in memory.....I traced my original problem to an open wire on the driver mirror.....It was of course the 5 volt supply wire...after fixing that the mirror works in memory.


Both my mirrors tilt down when you put it in reverse.....but when you take it out of reverse, they do not return to the memory setting.

So that has me stumped.

OK, so that narrows it to the HSMM then pretty much, since that is it's function.
(The mirrors would have to be 2001, since that was the only year to have them)
Assume that you've tried shutting the tilt off with the EVIC, and that works?

Do the two memory setting both work - I think you mentioned that they do.

If you'd like to try another HSMM, I can send you one, if it cures the problem, then we can work out an outrageous price, if not, return it.

Thankfully the Evic did shut that feature off, and yes both memory positions are fine.....Its just that damn tilt in reverse feature.

It is suppossed to return to your original setting isn't it?


If you have another module I think I would like to give that a shot.

Of course I would not ask you to send anything before I pay you.

Thanks

TFC, is there a possibility the gear signal on the '01 is enough different from the gear signal of the '02? '01 TCM/PCM, '02 HSMM ...

You got me on that one!! I would guess no...as mine is functioning fully with the exception of the 50% functioning tilt in reverse.

I would gather that the TCM/Pcm wouldn't factor in. I know there is a PCI bus connection involved, and somehow it knows when the car is in reverse...thinking thats via the BCM, but not sure.

My HSMM does know when the car is not in park, because I hit the memory switch while in drive.....and the EVIC chimed and said memory seat disabled, vehicle not in park.


So I know its getting PCI messages, just not sure which module it gets them from.

The messages are sent VIA the PCI bus, as you presummed from the cluster readout to the HSMM, which in turn returns the mirrors to which ever of the two setting is selected.
The 2001 signal should be sufficient, since it was a feature of the 01+ cars, shouldn't think that feature would be different especially since the tilt down feature does work.
Since the two memory positions both work fully, that would pretty much eliminate the mirror module from the equation, since it is only receives what ever signal is sent by the HSMM and positions the mirrors where ever they were previously set, and that is stored in the mirror module - similar to the multiple radio station settings - a radio function that is ACTIVATED by the seat module, not actually performed by it.
I'd say, that it is probably the HSMM.

If you want to "borrow" one and see, give me your address.
If it works, fine, if not send it back. I will send a 2002 version so that it will be programmed for both sides.

My tilt down feature works good on my 01 M and I have the OTIS. But maybe you need the EVIC on the Intrepid.

The OTIS doesn't have the feature of turning the tilt off for the winter, or if you don't like it. where as, the EVIC does.
YOu must disengage it by using your seat buttons.

Actually that may be the problem with yours K-nash.

Try this:

press and hold the set button (on the seat)
move the horizontal seat switch forward
then release both buttons similtaneously.


It is possible that there is a confilct in the EVIC & seat modules, so try turning the feature on with just the seat. You could also try it with the EVIC in the off position first so they'd both be in sync.
