Hi, I have a 98 Ford F150 Lariat 4x4 and for about the last 2 months I have had this power problem with accessories and some dash lights. what happens is sometimes after I start the engine the power windows and sometimes the wipers as well wont work. Then as i drive the 4x4 light in dash comes on and the Off light on the automatic shift handle blinks all the time. However the transmisson does not down shift when this happens. I know because when it happens at 65mph at just under 2000 rpms the rpms do not change. This will stop usually when I turn the truck off and later restart it, everything works fine. May not happen again for a week or so or it may happen again the next time I drive the truck.When this happens I do hear like an occasional clicking sound coming from inside the dash on the drivers side.Not sure if this may be a relay going bad or something else.The truck has around 168,000 miles on it and has the 5.4 engine. Any help figuring this out would be greatly appreciated. Thanks
