Haven't seen anything on this problem around here before...

My rear sun shade is currently stuck in the "up" position...it won't lower.

Anyone ever have this problem? Is there a way to manually lower it?

Can you hear the motor running? If so you might be able to nudge it down. If not you are most likely getting under the parcel shelf and manually rolling it around the spool. Just be glad it is stuck up rather than down. It protects your interior and mine is up 99.9% of the time. I only lower it to see if the thing still works.

Mine is stuck up too, I could hear the motor, but now don't hear it.

On a lark I got it to go down the other day and tried to replace the faded brake light but couldn't get it out.

I then got it to go back up, but it won't come down again, but I too rather it be up than down.

My "theory" is when the sunshade gets used so infrequently, the relatively poor conducting switch develops "flat spots" I call them - when I spray the sh*t out of the switch with MAF cleaner (squirt the tube thru the surround edges of the switch) while working it back and forth seems to solve my problems - it comes up every couple of years in several of my cars... when it goes away, it truly goes away and works fine.... maybe psychosomatic...

Not really "bad" lone failed, but kindof "flat spotted" and not as good of contact as it needs - in my case spray and working it back and forth has worked for me so far.

My "flat spots" are caused by "contaminates" or "debris"... Further analysis has shown it to be a mixture of coffee, sugar, and cream.

MAF cleaner is a pretty good choice as it dissolves the sugary goo. If you have tuner cleaner with lubricant use it as it helps prevent corrosion of the contacts.

Funny that this came back up today.

Yesterday I decided to give the button a shot and see what happens. It struggled a bit, but lowered the shade (after months being stuck up).

I haven't tried putting it back up to see if it will come down again or not.

+1 for fabbrisd1 and GreenZZZ, those switches attract incredible amount of dust, debris and liquid spills or drops. For a while ago my windows started to acting up, taking the panel off and giving the switches a generous bath with the maf cleaner solved the problem ever since. So if you take the cover off also shower the window switches too.

I wonder will some compressed air in a can work on/around the switch?

I don't have any at the moment but the fact mine went down and back up a while ago leads me to think the switch may be it.

Nope - compressed air doesn't really cut if - the trick is a can of MAF and spray the sh*t out of it while working the swtich back and forth - if you don't mind a mess most of the time you don't need to pull the switch panel - although pulling the switch panel is the very best way - you spray along the tight lines around the switch - sometimes attacking it a couple of successive days and delveoping patience is a good thing..

I call them "flat spots" since it normally comes from non-use..

No doubt... especially since it is right in front of the coffee cup holder.

Well guess what, I got mine working for 3 weeks. I was showing off my electronics debugging skills and now all I get is a faint click from the rear deck. :eek:

Nah...take the console apart and clean EVERYTHING with electronics cleaner...I keep a can in the arm rest for those days when the radio volume knob decides to go wonky. Works great.
