Ford F-150 4x4
 

I have a 1999 4x4 Ford F-150. The 4-wheel drive will not engage, and I dont have a manual to check the relay. Does anyone have a maual for this year of truck? I only need to knowwhich relay under the hood is my 4x4 relay.

You could get a Haynes Manual for about $16 that will have it in there.

What you might try is with some one in the truck key on foot on the brake trans in neutral engine not running tap lightly on the shift motor on the transfer case and see if it will shift, if it does you will hear a loud click. Some times when thease or not used very offen they will not shift. they tend to stick. good luck
