99 tacoma light issue?

ok i have light issue with my tacoma, first off when i step on the break the right signal comes on, it doesn't flash it just stays on. then when i make a left signal both signal comes on. i checked the fuse and light bulb and they are just fine, i don't have a check engine light on either? anyone here ever ran into issues like this? pls help i'm out of ideas!

oh i forgot that i also check the tow plug and the wires were fine as well, thanks for all the help!

 

I have a kind of similar problem.. When I'm giving it alot of gas in first, (revving to either 3 or 4k), the E-Brake light comes on for about 5 seconds or so then goes off again.. Can't figure out why..

 

99 taco dude: sounds like u have wiring issues. who installed ur trailor hitch wiring? someone messed up...

dhawk: check ur brake fluid level. when its low enough, when excelerating hard or stopping hard, the sensor will see the lack of fluid and turn the light on.

 

Sounds like your brake fluid is low. So when you gun it, you force the fluid to expose the sensor, thus setting off your e-brake light. Check your brake fluid level.

 

I agree with lotsoftoys.

Remove the tow harness and check. It sounds like your wiring harness has an issue with polarity, as in they plugs are switched. I'm sure the plugs on the harness should be keyed (only allowed to plug in one direction), but you may want to check.

Also, I've seen an improper ground kick my ass before. Double check your ground. In fact, disconnect, grind a clean spot on the frame and check your ground to that.

 

yea but i never had a problem with the tow harness before plus i never towed anything yet its pretty much not been used, i'll check grounds, thanks
