Just wanted to thank you guys for the reply on my 2000 ram that was blowing a fuse.
I still could not find the problems so I went to justanswerDOTcom and a dodge tech led me right to it.
he felt is was a short along the wiring harness somewhere..he was right!
it was a short caused by the air filter screw ( aftermarket airfilter) . a zip-tie holding the wiring harness above it broke and the harness was drooping and rubbed against it. when I pushed down on it ( while the engine was running) the fuse blew again.
replaced zip tie, taped up the wires and re-secured the harness--- good to go !
