Door Ajar - ZR-1 Net Registry Forums

DaveK · 05-31-2007

I've just started having problems with the 'Door Ajar' light coming on frequently. At first I thought perhaps it was me just not closing things quite right but now its appearing when I hit bumps in the road etc. The lights all flicker like crazy and I feel like I've been transported back to the disco era

I know there are the two door switches and one for the hatch. Are these servicable at all or is it just a case of replace the bad one(s)? Also, is there anyway of checking which is faulty or am I best just replacing all of them?

Thanks

Dave

I hate electerical issues! Dave by "they all flicker" do you mean all the interior courtsey lights or is it the Dash cluster lights, center display (DIC + Radio + A/C panel) also?

If it's just the courtsey lights I would say that the common ground would be the place to start. Did you have anything apart lately where you might have pinched a ground wire?

I don't know where the interior lighting is grounded but it's gotta go back to some lump o iron somewhere. This is a dumb suggestion....try checking the grounds at the back of the motor and look to see if we have any going to the frame under the car. Sorry man that's all I got without my FSM/electrical book!

Thanks for the reply Tom. Its the courtesy lights that are flickering - I should have made it clearer. I hadn't thought about the ground issue but that's a possibility too. I haven't had anything apart to pinch anything - the only thing I've done recently is added one of Marc's performance chips and the door thing was acting up before then.

I'll see if I can check the grounds, the door switches are available so I'll order some just in case.

Hi Dave

Oh, hey did you check the door lock cylinders. They have some electrical connection to the timer for the footwell & hatch & I think the rear view light.

Mine has a loose connection at the passenger door cylinder so when I put the key in to unlock the lights activate sometimes and sometimes not! Also I figure that the timer could be another source for a bad connection. Sorry again I should go look in the electrical book.....but I really don't want to take apart my door panel!
