i had the bed slid back on my 1998 gmc k1500 ext cab 4x4 to do some bodywork. all wires for taillights were disconnected. the next day when i put the bed back on and reassembled and reconnected everything i have these symptoms:

-no reverse lights
-when left blinker is turned on both rear blinkers flash dimly and the front blinker blinks fast as if a bulb is out
-when right blinker is turned on no rear blinkers flash and the front goes fast
-brake lights work but only when the headlights are off
-with headlights on there are no rear running lights or brake lights as mentioned above
-hazard flashers operate normally

any input is appreciated i have no idea what is wrong. i currently have the bed completely off and i do not see any grounds broken
