electrical issue turn signals

[bling]

my left turn signal blinks really fast and the right turn signal blinks normal

any ideas

also when i noticed the blinker issue my radio quit working and my cargo, dome, and under hood light all stopped working

i put new tow mirrors on my truck the other day and tested them out they are power and heated mirrors and it all worked fine. then one morning i went out to drive my truck and i noticed the power portion didnt work i couldn't move them with the controls and thats when i noticed my radio and interior dome lights and cargo lights werent working and i got the fast blink on my left turn signal.

so i checked all fuses and none were blown. so i pulled my cd player out to see if power was actully making it there thats when i noticed my 12v ignition wire had voltage(thats why the fuse was still good) but the constant 12v from battery for keeping memory was dead. so as a test i jumpered out the ignition 12v source to the constant and all my dome cargo and under hood light worked again. Then i went to try the mirrors and they moved for a second then it blew the fuse to the radio. ALL i know for sure is that the 12v constant for the radio memory is hardwired from the fuse box under the hood. its red and black and then changes to pink after the fuse box in the cab. This wire feeds the mirrors dome cargo and under hood light. I have been looking at wiring diagrams for like 3 hours seeing how it runs and im stumped on what is causing the problem. I feel like that pink wire has been broke some where in the dash and maybe shorted or went to ground.

sorry for the thesis but i wanted to shed some light so far

any ideas would be great

You are on the right track with the wiring issue, but have you checked bulbs? Normally a fast signal light in the cab means one or more blown bulbs.

my experience

Mine does that every once in a while usually when the tail light on that side isn't working properly or when the fuse is blown in underhood fuse panel. I have LEDs and have found out that I should upgrade my relay because of the low draw doesn't let the relay know they are working(I think that is what is going on).
This is just my experience maybe it will help.

well i did find that the tail light is out causing the fast blink so that knocks that one off the list but i think im gonna pull my dash out and chase that pink wire

the only thing i can figure is it is disconected some where or the new mirrors have a fault in them that burnt the wire up

im gonna plug my old mirrors back up and si if they blow a fuse

wish me luck
