Question about 1988 Ford Ranger
I have an 88 ford ranger that has the pushbutton 4x4, nothing happens when i push the range selector buttons, The transfer case motor was replaced with a new motor from ford, problem was not solved. A friend mentioned a control module,where is it located and how do I test it? Thanks.
The module is located behind the drivers side rear wheel "interior" panel cover. Not likely that the module is at fault. There is a small plastic ring that fits around a little metal stud on the electrical plate located on the transfer case side of that little motor that you replaced. If that little plastic ring is missing or smashed then that electrical plate rotates just a little too far and then it no longer touches where it should. Its like the power comes on when you first replace it but never again after that. Take that little motor off again and make sure that plastic ring is intact.

About 45% of all transmission problems are due to a defective battery, its components and the charging system. Make sure you have the correct battery in the vehicle and inspect all items relating to the charging system and the battery. The vehicle should charge between 13,5 to 14.5 volts. The condition of the belts is part of this inspection. If all of this is A-ok then get a scanner and pull the codes in the PCM.
Remember once light is illuminated for a item that item no longer works. Once you've gotton to this point let me know and I'll walk you threw it. Hopefully its just a weak or incorrect battery or something along those lines. Good luck and keep me posted
