High beam indicator remains on all the time, turns

The usual cause is a bad ground.
Check the ground with a test lamp.

mileage indicator numbers (or) not lit - are not lit . Proper term. odometer. Instrument cluster problem - solder joints break on these causing the numbers not to light . Problem with headlamps - headlamp module
The body control module (BCM) applies a pulse width modulated (PWM) voltage to the headlamp module and high beam relay in the underhood fuse block. The ground for the headlamp module is supplied from G113 or G115. For normal manual low beam operation when the headlamp switch is place in the HEAD position, ground from G202 is applied through the headlamp switch and to the BCM through the headlamp switch headlamps ON signal circuit. The BCM then applies a PWM voltage to the headlamp module/high beam relay voltage supply circuit. The headlamp module then applies battery positive voltage through the left front (LF) and right front (RF) LO Beam fuses to the left and right low beam headlamps. The ground for the left headlamps is supplied by G101 and the ground for the right headlamp is supplied by G100.
For high beam operation, ground is applied at all times to the headlamp dimmer switch from G202. When the headlamp dimmer switch is placed in the HIGH position, ground is then applied through the headlamp dimmer switch signal circuit to the BCM. The BCM then applies a ground to the headlamp high beam relay control circuit. This energizes the HI Beam relay, the relay then applies battery positive voltage through the LF and RF HI BEAM fuses to the LF and RF high beam headlamps. The ground for the left headlamps is supplied by G101 and the ground for the right headlamp is supplied by G100.
The BCM then sends a class 2 message to the instrument cluster in order to illuminate the high beam indicator lamp. If the headlamp switch is left in the HEAD position, the inadvertent power control feature will turn OFF the headlamps after 10 minutes after you turn the ignition switch to the OFF position. If you place the headlamp switch in the head position after the ignition switch has been turned OFF, or if the ignition switch is in ACCY position, the headlamps will remain ON until you turn them OFF or until the battery runs dead.

Hooking up an OBD2 reader will tell you right away if the BCM is shot or BCM. Take it to advanced auto or O'Riley's they will hook up a an OBD2 reader and tell you. Sounds like a faculty PCM and BCM to me or just faulty PCM since you've replaced the Body Control Module already.

high beam relay might be stuck on

this should help.

You can't turn them on manually with the switch . You have the switch set on auto ?
Headlamps
You can use the headlamps in two different ways.
• Place the headlamp switch in the ON position for normal operation.
• Place the headlamp switch in the OFF position for automatic lamp control (ALC). During ALC the high beam headlamps are On at reduced intensity for daytime running lamp (DRL) operation in daylight conditions, or low beam headlamps On in low light conditions.
The DRL/EXT LTS fuse and the EXT lamps fuse in the underhood junction block supply battery positive voltage at all times to both of low beam lamps and to the right high beam lamp. The low beam circuit continues to the high/low beam switch, then, depending on the position of the dimmer switch, connects to the normally-open headlamp relay switch contacts. Placing the headlamp switch in the HEAD position provides a ground path for the headlamp switch input of the Body Control Module (BCM). After receiving this input, the BCM energizes the headlamp relay. When the headlamp relay is energized, the low beam circuit is connected to ground G201. The high beam circuit is divided into a left and a right side circuit.
The DRL/EXT LTS fuse in the underhood ignition block supplies battery positive voltage to both the coil and to the normally-closed contact of the DRL relay switch circuit. During high beam operation, the left side current flow is through the closed contacts of the DRL relay, and to the left high beam lamp.
The EXT Lamps fuse in the top of the engine fuse block supplies battery positive voltage to the right high beam lamp. Both high beam circuits are then connected together, and continue to the dimmer switch. When the driver closes the high beam contacts of the dimmer switch, the circuit is grounded at G201.
Both the headlight switch and the BCM provide a ground, or control circuit, to the headlight relay coil circuit for manual or automatic headlamp operation. When you place the headlamp switch in the OFF position, and the ambient light sensor indicates low light conditions, the BCM energizes the headlamp relay for low beam operation. You may switch the headlights to high beam by pulling the dimmer switch handle toward you until the dimmer switch is activated. When the dimmer switch is placed in the HIGH position, the indicator lamp input to the BCM is pulled low. The BCM then sends a class 2 message to the instrument cluster in order to illuminate the high beam indicator lamp.
If the headlamp switch is left in the head position, the inadvertent power control feature will turn off the headlights 10 minutes after you turn the ignition switch to the OFF position. If you place the headlamp switch in the head position after the ignition switch has been turned OFF, or if the ignition switch is in the ACCY position, the headlights will remain ON until you turn them OFF or until the battery runs dead.

Looks like the dimmer switch is built into the combo turn signal wiper switch on the column.
I would unplug that switch and see if the indicator light goes off.
If it does the problem may be inside the combo switch.

check the fuses first, no luck replace the day time running light module.

Your switch must be working since your indicator is telling you when the high beams are on, so my guess is that your bulbs are faulty. The high beam part. They probably burnt out one at a time, so you didn't notice until the second one went. Change your bulbs, and see if that solves it. If not, let me know.

My lights have had this problem for months. From time to time I try to fix it, but I have learned the following:

1. [EASY SOLUTION] After turning off the car and turning off the headlights, when I pull the headlight switch back (toward me) and then let go, the running lights turn off. [/EASY]

Extra information that I haven't figured out how to use yet:

2. Apparently the DRL bulbs operate through the high-beam bulbs; this is why you get the high-beam light when the DRLs are broken (or whatever) and why you can turn them off with the high-beam switch.

3. My wife took the car out for a fluid change once and said the mechanic pointed at a light on the car and said, "that bulb's out," and that if she fixed it the DRL's would work normally, but she forgot which light it was. He even told her what bulb it needed. I took it to the same place and no one knew what I was talking about.

I don't think about trying to fix this very often since I realized I could turn the lights off with the high-beam switch. I used to worry that that blinker was somehow draining the battery, but it never has (whereas I once drained a brand new battery just by leaving the interior light on all night). I hope I've helped!
