Wiper problem-93 Ford Ranger XLT,2 wheel drive,3.0 v-6.auto. Only have high speed,no more intermitent,no longer returns to start position-HELP

The problem would be in the stalk controller. The wiper Relay is what provides power to the motor for all settings, the delayed wipers, low speed, and high speed. There are not 3 relays, but 1 for all functions. If you have power to the high setting, the relay is working.

Start truck shift into neutral. Push button for 2 wheel or 4 wheel high. Should go into that range. If not you have other issues to discuss with us.

Study up on what an Idle Air Control Valve does then make your decision. They can be expensive.

You don't have to put the wipers in an upright position You can take the arms completely off. It's very easy to do, when you are looking at the base of the wiper arm, on the side closest to the windshield, at the base, there is a spring-loaded tab. Lift the arm on its hinge to where the arm is now pointing away from the windshield, pull the tab and the wiper arm will slide right off. Now you can access the linkage joints easily. Hope that helps!

Check your rear end to see if you have a sensor like in this video, if so it could solve some issues. The video describes items all going out around the same time. Its based on a 2 wheel drive but who knows you might have the same sensor in the same location. This is a shot in the dark, but who knows it might help or point you in the right direction.

Check your operator's manual. Make sure any and all fuses that have anything to do with the affected items are not blown and are working properly. If you can; check for loose fuse connections or wires. Hope this helps. God bless!

You pretty much answered yourself here, the switch sounds like it is going bad.

that sounds pretty high, I had those replaced on my 99 ranger XLT and it only cost me $400.oo, in Naples, FL. Id definately shop around.

The 4x4 system has a controller,or computer,called the Body Control Module and there will be stored trouble codes.To work on a system that's electronically controlled,you have to get the codes from the system.Every trouble code has a diagnostic route to follow to resolve the faulty component.I have read about Explorers having faulty door open/closed sensors.These set a code in the Body Control Module,and in the process,the BCM inhibits 4x4 operation,causing a no 4 wheel drive complaint.There is also an electric motor on the transfer case that can fail electrically or mechanically,along with speed sensors and fork position sensors that can give trouble.

Replace the brake pads, then sand the lines and spray them with undercoating. If you dont want to sand lines just spray the undercoating. They will last longer if you sand them. This is available at your local auto parts store
