Interior Light Problem?

Ok Everyone. I have a 97 GL and have had lots of problems with door ajar chimes and interior lights being on.

I used WD-40 on the latches and it quit up until about a week ago. Now the ajar light does not come on but my interior lights stay on all the time while driving. When you open the door the ajar light will come on so I am sure the light is not blown. I tried the WD-40 on everything again but to no avail.

Any ideas on what this could be this time?

i think is the time to replace the door switch

Replace all of them. My 97 Sable had the same problem until I had them all replaced. I bought it used and the dealer paid for the fix.
