I HAVE BLINKERS AND BRAKE LIGHTS NO RUNNING LIGHTS THOUGH I TRIED TO FIND A PARK LAMP FUSE BUT UNABLE TO WHAT DO YOU THINK?

Check the wire grounds where the lens connect to the vehicle. With a test light check to make sure current is arriving at the bulbs. If not, then follow the wires back to the light switches.

This post has a few suggestions that may help you find your problem.

Check the parking light fuse first. Then check to make sure the switch is actually providing power to the circuit

Year Make and Model,???
Your problem is in or under the fuse box.

Sounds like brake pedal switch

The tail lights are also called parking lights.
There is a 10amp fuse for each rear parking lamp. The fuses are in the rear fuse box. Your owner's manual will tell you where that fuse box is located.
The fuses get power from a park lamp relay.

Park, Tail, Marker Lamps, and License
The park, tail and marker lamps, including the license lamps, turn on when the headlamp switch is placed in either the PARK or the HEAD position, or anytime the headlamps are requested. The RT I/P #1 fuse in the RH I/P fuse block supplies battery positive voltage to both the park lamp relay switch contacts and to the park lamp relay coil circuit. The park lamp relay coil is controlled by the body control module (BCM). When the headlamp switch is placed in the PARK position, the BCM energizes the park lamp relay coil control circuit.
Current flows from the park lamp relay switch to both front and rear park lamp fuses and to their respective park/tail lamps. The front park lamps are grounded at G101. The rear park lamps are grounded at G302. The license plate lamps are a part of the rear park lamp circuit and are grounded at G302. The inadvertent power control feature prevents the park lamps from remaining on more than 10 minutes if left on. If the park lamps are turned on after the ignition switch has been turned OFF, or is in the ACCY position, they will remain on until turned off or until the battery runs dead.

Did you the REAR PARK LP fuse 15 amp in the right insturment panel fuse box.

Someone replaced a dual-filament brake lamp bulb with a 'single' filament bulb.

Both the tail light /dash lights are the park lamp connection of the car as the fuse is seen on the same place where the other fuses were located marked as park lamp.
It will be easier to check the supply to the park lamp with a multimeter to confirm if the voltage is coming over when the switch is activated, if not the ground connection can be faulty, use a ground to check and confirm to the tail lamp. make sure the park switch is working and is not faulty with the meter.

sounds like you have a short or defective headlamp switch switch contacts are probaly grounding internaly to hot
