ok so this is the deal i have a 93 full sized blazer and i cant seem to figure this one out... i had to replace my whole front end clip... i did everything right and didnt have a problem with putting everything back together... so when i first put all the wires back through the radiator support and turned on the lights and signals everything worked fine but now after that i put the radiator back in and the fan gaurd, i had to hit the horn button once to get the lights to turn back on and then my left turn signal blinks faster (lights are all working) and my wipers turn on. also...

@ turn on lights = right blinker stays on
@ turn on highbeams = all lights are fine (left blinker still have a problem)

 

Did you disrupt one of the grounds while installing the radiator? Pinch some wires maybe?
