That sounds like you just have a short in the turn signal switch, have you tried replacing that yet ?

No but why wouldn't my turn signals come instead of jus my tail lights
Automotive Expert
its just how the switch is shorted, it sounds like a low voltage short to the brake lights circuit

My knowledge and capabilities and access to tools are limitless... I've been a mechanic for the past 25 yrs this jus has me stumped
Automotive Expert
I would start with replacing the switch first

I have led bulbs in my tail lights and regular 3157's in my turn signal bulbs... would that create a problem
Automotive Expert
it shouldnt, did this happen when you replaced the lights?

No this is the 3rd or 4th time.... my hood is up and it rained all day so I started at fuse box cause it was wet
Automotive Expert
if your moving the switch and its turning off that would indicate a issue with the switch

Ok there off now and they stayed off when I pulled the switch down (left turn) but not upI jus need to try the turn signal switch
Automotive Expert
yes replace the switch

Ok thanks a million
Automotive Expert
