A few things....you could PM the other poster that had this issue and see if they got it resolved. Definitely start with the cheap/easy stuff like a brake switch and/or lights. Get an IIDTool to help troubleshoot.

Have you had water intrusion? If so...that's a great place to start.

 

Just to update everyone-I corrected this issue on Sunday, it ended up being two of the common corroded splices in the massive wire loom on the passenger side. I had this issue resolved and also an airbag light that kept occurring as well, so now my dash is light free, besides my pesky air suspension random fault. I hope this helps someone, and thanks everyone who tried to offer some advice!
