2001 Quest parking lights wont shut off..... HELP

tcpastrano

hello all. I have a 2001 quest/villager and the parking lights will not shut off. checked all fuses and relays and was led to headlight control module. pulled the lcm out... lights still on. so.... is it smart entry control module? body control module? if this vehicle even has the bcm. i have looked all over online as to its location but too no avail until later models. any help would be appreciated. I do have the auto light option on the vehicle as the sub class is villager estate but even when i bought that brand new switch and had the other in my hand completely disconnected the parking lights were still all on. HELP please.

In the dash fuse box to the left of the steering wheel, what happens if you pull fuses #17 and #19 ?

if i pull 17 and 19... i believe that is the front corners and tail.... the front goes out but rear tail lights stay on. yes. i am positive it is tail lights and not brake lights. i wish i was that lucky. lol.

Fuse 17 is the front parking lights, and fuse 19 is the rear. With fuse 19 pulled the normal circuit to power up the rear parking lights is disabled so if they are still on then you have power being supplied improperly from an unknown source.

One possibility could be if you have a trailer hitch harness attached to the vehicle. If you do, try disconnecting it and see what happens. Otherwise the next thing to do might be to pull fuses one at a time to see which one is supplying the power that is being fed into the lamp circuit.

Just a note, the nickname for a failure like this is a "sneak circuit."
