Recently reported EXTERIOR LIGHTING problems on 2003 Ford F-150

My 2003 f-150 v8, 4.6l 2wd truck received water damage to the gem (generic electronic module) causing the windshield wipers to stop working while driving to work on a foggy/dew morning after a rainstorm. the water damage was due to a leak on the loose windshield that caused water to run directly to the fusebox & gem that controls all electronics in the vehicle. after looking seeking an answer for this problem, i found that at lease a hundred others have had the same windshield leak in the '97-'03 f series vehicles. the gem could and has caused vehicles to shut off and on and have lights go off and on at a random time if it received water damage. it is very dangerous and needs to be fixed immediately. the windshield is a common problem and many others have suffered from the same problem as me. thank you for your time. *tr

Tl* the contact owns a 2003 ford f-150. the contact stated that while making a right turn, the turn signal would not activate until the steering wheel was raised into a higher position. as a result, the vehicle was nearly involved in a crash after the contact almost lost control while turning. the contact also stated that the wiring in the signal lever was not connected to the steering column whenever the column was shifted. the manufacturer was made aware of the failure and stated there were no related recalls. the failure mileage was 145,000.

My ford f150 super crew has a recurring problem in that it continuously blows a certain 5 amp fuse. this fuse disables the automatic lights, the automatic door locks and the overdrive system. i took the truck to the local ford dealership. they replaced the fuse and charged me $52.50. they did not fix anything. i found an identical complaint on your website from nov 30, 2008.

The multi-function switch on my 2003 ford f-150 harley davidson is faulty. it fails intermittently causing the left turn signal to not function at all. it affects the hazard flashers as well. it works only intermittently and then fails again. i have had no accidents and the vehicle had only about 48,000 miles when the failure started. i have almost been rear-ended several times due to the left turn signal failing. *tr

Recently, the headlights, fog lights, dash lights, auto light functions, door locks, exc., all began perform erratically; including the dash lights going out while driving at night! the next day i went great lakes ford in ludington, mi. as soon as i mentioned one of the symptoms, the tech immediately knew the problem: he told me that the oem adhesive on the windshield had failed causing water to leak down behind the dash and directly onto the gem module and fuse panel. he said he has seen this problem over and over with this year f150 and had probably fixed more than 100 over the last year or two. the local windshield shop, duneside auto glass; the owner told me that they have done more than 25 windshields this year at great lakes ford for this exact same problem. i check the ford websites and also found that there is a tsb listed for this problem. the cost of the repair was $1200 which included $500 in parts for the box asy, module and new light switch,$351 in labor and $325 for a new windshield plus taxes. how can there not be a recall for this? if the problem is that prevalent at a northwestern michigan ford dealer, it has to be everywhere else in the country. *tr

Vehicle type - 2003 ford f-150 (harley-davidson edition) issue also affects other year models of the same truck. 1) no known events - part seems to have broken easily under normal use and normal driving conditions. 2) the part that has failed is a fog lamp bracket. when the bracket fails (it is made of brittle plastic), the fog lamp assembly will fall to the ground in front of either the left or right front tires. this can cause a loss of vehicle control when the truck tire impacts the fog lamp assembly. 3) ford will not replace the part - they disagree that it is a safety hazard. there are several reports of these parts failing online in different user forums. *nm
