Drivers door window trouble

[DaveE]

Sometimes when I open the door the window won't drop the little bit it's supposed to. It can be either from the inside handle or the outside handle. Sometimes it'll drop and come back up quickly too. Sometimes it works fine. What controls this? Is there an adjustment somewhere? Has anyone else had this problem?

It's an early '97 2.5 Boxster 5-speed by the way. Thanks in advance.

Without a wiring diagram that's tuff. A DMM (digital multi-meter) also helps much if you know how to use it. Your problem is most likely a bad connection. There is one at every stop in the circuitry. It probly makes a dozen stops including at the the little black security box under your seat, switches in the handle, the top latch, fuse, relay(?), and god knows where else.

Without a diagram kinda shooting in the dark. You can start with place you know there is a connector, just unplug and replug them , jiggle it around and see if anything happens. You might get lucky.

It is likely the switch on the door handle - or a bad regulator if the window has other problems.

There is just 1 switch for both the inside and outside door handles?

If the problem occurs on both handles, inside and outside, the lock itself could be the cause.

[DaveE]

The problem does occur on both inside and outside handles, intermittently.

Dave:

There are three microswitches that control the drop-down feature of the window (for that 1/2 inch drop, not for the 4 inch drop when you pull the top latch open):

One behind the inner door handle, one behind the outer door handle, and one inside the lock assembly.

The symptoms you describe are consisitent with the one in the lock assembly. That microswitch may be bad or there may be a loose connection there.

You will have to open the door panel to access and/or repair/replace.

Well if "intermittently" means one (door handle) will work and other won't (on the same door), or vice-versa, that's one story.

If intermittently means that on occasions neither works at all, but at a another time, they both work (same door), that's a different story.

This bit of info would help alot, me anyways. But I have run. right now.

Maurice nailed it. If you have some feel feel for electricity, with Maurice s input you know what you need to sort it out. If you don't, you'll be stabbing in the dark but, you'll have the amo to point a regular mechanic into the right direction...quickly and inexpensively.

Thanks for the advice! It seems that when one handle doesn't work to drop the window the other one won't either. I'll remove the door panel and have a look at the lock micro-switch. I have a copy of the car schematic somewhere to help. I wasn't sure which components were involved but your info should help.

Thanks everyone!
