I can sympathize. Back in 2014 I bought a 2009 Ford E-250 full size van that had the $50 factory option DRL function. I printed out the window sticker from an online source based on the VIN, and there it was under factory options: DRL: $50
Daytime Running Lights.
I did not like them because at night, if the engine was running, and you had your normal headlights turned off, as in parked with the engine running, or say, slowly backing up, whenever, the dang headlights (but none of the parking lights) would go on when selecting 'Drive' but go off when you switched into 'Park'. So, as you jockeyed around, such as hooking up to a trailer, or moving the vehicle slightly at a campsite to get level, etc, the stupid headlights would go on, sometimes pointing right at people in the dark at a campfire, or beaming into someone's RV or tent. Then go off again when you selected 'Park'....Then go back on when you selected 'Drive'....It was STUPID...and embarrassing.
I found all kinds of information on the internet about it, with answers like 'press the parking brake down a notch', NOPE. Didnt work. Or, 'look for the relay or fuse behind the radiator or near the firewall'...NOPE. Didn't apply. Wrong year vehicle.
Turns out it was a programmed feature in the PCM, Powertrain Control Module. And I went to 3 dealers who told me it cant be changed, two of them hooked up and tried. One local dealer refused telling me it was ILLEGAL to defeat the DRLs.
In Texas, and most of the USA, DRL's are NOT required. Duh. Bad dealer, no donut...(not yet, anyway)
After a month or so, I ran across an obscure Ford Ambulance Chassis/Van TSB online that had all the pertinent information, including the software codes and the so called 'Ambulance Settings' buried in the Ford dealer software. Included was a statement by Ford that the modification was legal in most of the USA, including Texas. (BTW, my van was never an ambulance)
I printed it all out and wandered into the local dealership that had previously told me it was 'illegal' to turn off the DRL function.
The service manager looked it over, asked a tech, and 15 minutes later, they had hooked up their shop computer, and PRESTO!....all done. No more DRL function. They charged me $50 which I thought was very reasonable.
So total cost to turn on DRL and then turn them off again: $100.
When engineers at Ford think they 'have a better idea'....I say BS.
I hope you can get your 'Approach Lights' figured out...it is frustrating.
