so i put 2bi-xenon 8k high/low hid's in 04 ranger and right after installed notice this problem the high beams are on with the low beams are on and when i flip to high beams the hids switch to low beams so the problem

 

you have them wired wrong, they need to be wired from left to right
White, Black, Red

 

i have one blue connector with 3 wires blue, white, and brown , and ive already tired switching the blue and brown , cuz white is ground

 

are you sure white is ground and not Brown?

 

check on motor alldata and the factory ground is the center which would be white for the aftermarket blue connector.

 

What brand of HID's are they?

 

their 2bi- xenon hid converstion kit... so i figured out the problem the wiring for the hid blue connector was wrong right out of the box... so factory female plug is lg/bk(L), blk(center), dblue/lg(R), high-grd-low, and the blue connector is now white(L), brown(center), Blue(R), problem solved....

 

Yeah I have got a similar problem. I installed this...NOTTOŽ SE - Complete HID Conversion Kit - 2001 Ford Ranger HID Kit...today and I have great output, but it only stays in high beam mode, even with switching from high to low with the turn signal/windshield wiper control arm. I will take this info from this post and see if I can't tweak with the blue connector cause I am pretty sure that's where the problem is. I have triple checked all wires, I have grounded everything extremely well, and made sure the ballasts weren't getting too hot and after 5 hours, still no avail. Simple plug in and enjoy my ***...
