ok started driving home yesturday, all of a sudden ABS light turns on, speedo drops out to 0. a/c stops working, blower worked just compressor shut off, turn signals wouldnt work and overdrive light flashed. it would do this all the way home it would all come back then all act up again, had trans not shift into overdrive one time then after that worked fine, seems electrical. anyone know were i should start looking? now i dont know if this body style has the same issue with water leak on gym module like the 97-03 f150. it hasnt happend till yesturday and it was raining all day? someone shove me in the right direction, i dont see anything abnormal. checking codes tomorrow. Thanks

 

Nobodys Got anything? only codes I have is a vehical speed sensor fault code p0500. other than that nothing. So that would explain my speedo dropping out but doesnt explain the other concerns with it. seems like a GEM module to me. anybodys input would be great

 

Maybe moisture in the fuse block?
