'98 1 Ton dually 4x4

[nomemama]

My ABS lite came on along with the Airbag lite. The speedometer dropped to 0. Then the lites went out and everything was OK. Later it did it again. Yesterday coming home it did it again and they wouldn't go out so I stopped and turned the engine off. Then I kept all unnecessary lights off. Finally I had to turn on my headlights but it didn't do it again.

Sometimes when I put my beams on bright more often than not by headlites go black. That is scary! Doesn't happen everytime but it makes me so goosy that I don't turn turn on unless the moon is full! Dodge replaced the switch one time.

I am an RV transporter with 280,000 miles on the truck all but 50K put on in the last two years. Same engine and transmission. Replaced 3 transmission sensors, larger oil pan and a temp gauage but problems yet. A little slow to change into the highest gear but works soothe, so far. No work on engine,yet.

Please help. Since fuel is so high I can't afford a Dodge dealer repair right now. Thanks for any help.
