Question: Park brake light

[stiffler]

I have looked and have not heared of any one with this issue. At night truck off ,key out of ignition, The park brake light on dash is on but dim! Start truck it goes bright on dash self test. This is on dim all the time and it is starting to get to me . Any one got an idea?

unplug sensor in master cylinder and parking brake see if it changes. Thats where I would start

I will try and see. I did how ever replace the master this summer issue was there before and after! Thanks for response let you know what it does.

I unplugged sensor on master all it did was flicker! But it is on dim all the time but goes bright on start up for dash self test. Power back feed ? Bad ground some where?

The brake light on the dash is controlled by the cluster logic. Sounds like the cluster is starting to fail.

It has been lke that for a year or 2 ! How long do you think it will last?

Not sure how long it will last. However, these trucks drive fine without a working cluster, so I say run it until it fails, then get a new cluster. No point replacing it now unless it is draining your batteries.

Is there a way to verify cause? I hardly drive it and little things just irritate me. I wasn't thinking of it being a cluster issue. If that is what the issue is I'll keep running it. I will spend my time researching my next upgades Tranny in near future!!

anyone around you

See if there is anyone around you with the same cluster and swap them. I had an issue (on my Suburban) I thought was an ECM so instead of buying a new one a guy from work cam over with a Tech tool and his ame year suburban and we swapped ECM's and my issue was still there. We found out I had corrosion in a plug under the left kick panel and repalced the plug ($9.50 part) and everything works perfect now. just a thought!!
