The brake light and abs lights stay on on my 1999 dodge 1500 van

As far as the cruise control look under the battery, drivers side one if a diesel and there is a vacume line for the cruise. This vacume line always breaks right under the battery causing the cruise not to work.. Ive owned 2 2nd gen dodges with non working cruises and this was the problem on both.

I would still be suspect of the ABS module. Had the same thing happen on an 01 Tahoe.

Search the web for an ABS repair facility located in Russia, IA. They repair the module for $150.00 and give a 5 year warranty, which you can't get from the factory.
And, their website has troubleshooting guides to help you determine if for certain the module is bad or has a probelm.

You can remove the module and continue to drive the vehicle. Their turn around is as they state, and once I had them make the repiars, my Tahoe has been up and running great!
