ebrake light won't turn off.
My ebrake light will not turn off. I searched and performed the following fixes to no avail.
Topped off brake fluid to MAX line.
Flushed old fluid with new fluid, cleaned cylinder, bled.
Poked floater, seems fine.
Unplugged sensor on master cylinder still does not turnoff when unplugged.
Checked brakes for hydraulic problems. None.
Tested if softtop works with ebrake down. It doesnt.
I noticed when I pull the ebrake up the brake light gets brighter and when I release it it dims.
Checked for loose connections under center console.
Any other ideas?

Remove the master reservoir connector again. Check for continuity on the two pins connector...cylinder side. It shoul be no continuity with fluid. My guess is you will have continuity which means your float is stuck. There is a small rib on the inside of the firewall side of the reservoir and a matching cutout on the float. Sometimes the float binds at the top. Look closely here if you have continuity....a poke will fix it but you need a carefully placed poke.

Where is the ground for the ebrake?
#7
There are 3 items in the e circuit. Don't bother looking for a ground issue as this circuit grounds into the B Dash Harness. If the ground were bad you would have a bunch of issues.
The first element is the float switch which you have tested half of. But you have checked the important half ( the other would activate the light if you were low on fluid).
The second element is the brake switch. This is located at the base of the E-brake. It will be a clear 1 pin T connector. You need to pull the center console cover to expose this connector. Check for continuity between the switch side (not the cable) and ground. With the brake lever up there should be continuity. Brake lever down there shoal be NO continuity.
The third element is the convertible control module. The module is located behind the lower passenger knee panel (below passenger air bag). There are two grey connectors. I think the left one is 14 pin and right is 10(?).Reseat them (disconnect battery for this and the next one).
The last connector of concern would be the 404. This carries the ground wire between the dash B harness and the actual Ground. Looking up from below the drivers footwell you will see the plastic piece below the steering shaft. It's the one that pivots and has a bunch of holes through it. On the drivers door end of this plastic you will find 3 light blue connectors. The one in the middle is C404 and carries the e-brake ground wire. Reseat.
My guess is it is the e-brake or float switches.
