Power windows and blower motor not working Speedo not working and ABS light and brake light and air bag light on 2001 Dodge Ram 1500. I changed the speed sensor and the abs sensor also have new ignition switch. Still no good. I see lots of people have same issue but no fix.

 

You have multiple issues. Take them one at a time.

For the speedo, if the PCM isn't getting a signal, there should be a code set, is there?

 

No code. This all happened at once. Runs and drives. After starting it rolled driver side window down and wouldn't go back up. Notice the lights on the dash and heater blower not working.

 

Checked all fuses and all okay. Not getting power to the power window fuse spot. I think there is something wrong between the ignition switch and where it goes next.

 

Power windows,and Blower are not on "fuses" they are on relays. those metal fuse looking pieces and the black plastic cube looking ones are all relays.
Windows Up are on one relay, and windows down are on a different one.

Hope that help a little because I can't really be much more specific.
Also some of the interior circuit (iirc) is fused or relayed in the underhood fuse block.

 

Fan motor is on a relay too. Interior fuse panel.

 

I have been studying the wiring diagram and the black and orange wire from the ignition switch supplies the power to all the thing I am having trouble with. So Iam going to try and trace this wire to the fuse box.

 

sounds like a reasonably good good idea, but it is a PITA place to start looking for issues in first.

 

Perhaps you lost a ground. There are grounds attached under the driver's kick panel and behind the plastic panel. Also under the hood near the brake booster and on the radiator support. Also by the PCM against the firewall. Check everywhere you can.

 

Thanks guys found it. The black and orange wire had a bad connection. Tighting the connection and got power on it. All so the 30 amp fuse that feeds that wire was ever so slightly blowed. Could barely see it. When you took it out to checked continuity it would give false reading loose inside fuse. Again thanks for y'alls help.
