Went to our other house today so was really happy that I got to see my Esprit!
Anyway, took some pictures of the parking brake switch area in hopes that it might be helpful to somebody. The pictures aren't the greatest...I took a ton, but for some reason, because of the small square opening that I was shooting into, the camera did not want to focus on what was in the opening due to the close proximity of the surrounding area. Regardless, I think they will give you a really good idea of what to look for
After opening the door, without getting into the car, stick your head in and...
1. Locate the carpeted area directly below and to the side of the parking brake handle
2. Remove or pull the floor mat to the side to the right, away from the parking brake area
3. Pull up on the factory floor carpet of the Esprit and pull it to the right
4. Now that the floor carpet is out of the way, pull up on the carpeted area that is covering the side directly below the parking brake handle on the right side.
5. When that side carpet covering is lifted upwards, a small square or rectangular opening will be exposed. It looks like someone at the factory cut a hole in the fiberglass. Inside that small opening, you will see the parking brake mechanism and towards the base, the microswitch (it's hard to miss) which has wires and connectors coming off it.
6. Check to see that the connectors are firmly on the spades and that the wires are properly crimped onto the connectors. In my case, the wire was too short and kept pulling itself out of the connector until I finally used a new connector and a short length of appropriate gauge wire to extend the existing wire so that it would no longer be stressed.
7. Chances are that the connector has come loose or the wire has come out of the crimped connector thereby no longer illuminating the parking brake indicator when the parking brake is on.
I'm no expert here...just trying to be helpful and hoping it might help someone out...it worked for me.
