Seeing as you replaced it but the light still doesn't come on, check your work.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I could use your help chasing down a solution.
Last weekend, I wanted to open to clamshell to check to see if the rear drains were clear. I put the parking brake on, opened the convertible top latch and pushed the button to lower the top. Nothing happened. No parking brake light, no window drop and no motor sounds.
Yesterday, I replaced the parking brake sensor switch. Now when I put the brake on, open the latch and push the button, the top will open. Still the parking brake light is out and the windows won't drop.
So my next task will be to change out the micro switches next to the convertible top latch. I expect this will fix the window won't drop problem. My question is will this fix the parking brake light out problem?
I know the light works because it comes on when I first turn the key in the ignition.
Thanks
Found several codes. They were:
33 - interior sensor faulty
42 - wrong key or transponder pill
60 - central locking limit position Lock not reached
None of these seem like the problem unless the interior sensor and the latch micro switch are part of the same unit
The brake has a sensor. If the light isn't lighting up when you pull the brake then that sensor needs replaced or the top won't operate. Seeing as you replaced it but the light still doesn't come on, check your work. Maybe test the relay with a multimeter?
If the light is good, and the sensor is good, you should see that light up when you pull the handle.
Here's where things stand now
Parking light on when I first turn the ignition key; goes off when engine starts
Convertible top and windows work normally
Tested the convertible top relay with multi-meter, all tests were normal
No parking light when engine is running and I pull up on the parking brake
Am I right that the light should come on when I pull up on the parking brake? If so, where should I look next.
Thanks
Thom - disregard my last message. After a quick search, I see that you have a 2001. The correct pin on the cluster is #22 on the blue connector. Same procedure as described in my last message. With the DVM or test light attached as I described, pull the brake and release it to confirm that it is switching correctly. If not, you have a break in the wire between the parking brake and the cluster.
If it does switch properly, the problem lies within the cluster.
This is a source reference. Confirm exact model applicability in the original material.
