multiple electrical issues
 

My 98 Dodge ram 1500 5.9 4x4 has no speedo, cruise, airbags , windows won't roll down, no reverse lights won't start with out the starter hooked to a switch and no blower motor

Pull the main connector on the firewall and look at it.

Ok. because I do have power to all my fuses just not pass the firewall seems like

pulled all three plugs from ECM none are corroded no dirt no moisture I live in Wyoming so there's very little moisture but this did happen after its snowed about 2 weeks ago I've checked multiple plugs under the hood none have water corrosion

Power to which fuses? The ones in the side of the dash, or the ones under the hood?

both fuse boxes all good , I've checked every fuse on this truck

Does your horn work? All the things you mentioned work off the ignition switch. Might want to look there.

Horn works I've tried an ignition switch power to both fuse blocks

Constant or with key on? You need to check that you have power(key on) to(and after) the fuse for power windows, radio & blower motor. These all get power after the key is on.

My stereo hasn't quit working. is there a possibility that I get a bad ignition switch and it'd be a good idea to try different one just wondering? Came from auto douche bags
