Question about 2003 Ford F150 Regular Cab
When I select 4HI Indicator light comes on but front wheels won't engage. Fuses and re4lays check out. One minute fine the next it was not working. Any ideas out there?
I had the same problem... even though i have an 04 heritage edition 4x4, manual shift lever, this should help you out... on the transfer case, there should be a plug just beside the forward drive shaft... even though mine is a manual shift, that plug lets the computer know that you are in 4wd... you also have a vacuum locking forward differential, the plug i referred to tells the computer to activate the vacuum system which engages the forward diff... i'm going to take my best guess that either the plug assembly on your transfer case might be bad, OR, you might have a bad vacuum module on your forward diff - even possibly a vacuum leak in the air lines coming from that assembly up to the firewall on the passenger side... just take a peak and see what you think, both the plug and vacuum assembly are easy fixes... (by the way, the vacuum module is a cylindrical unit that has an arm coming out of it that enters the diff... the module should be mounted directly onto your forward diff.)
