    My blinkers and hazards work fine until i hit the brake pedal and then the signals stop working and the brake light takes over. /forums/images/graemlins/confused.gif When I take my foot off the brake pedal....the turn signals work again. It is the same for both sides and the hazards. So I replaced the bulbs thinking that was it, but same thing, did not fix it.
    Does anyone have any suggestions? Also, I have not done any steering column work, light work, or wiring work lately.

    Well, this is common in older vehicles. I've had about 4 pre-1980 cars and trucks and all of them did this, so I thought it was just normal. Yours being an 89 though, it probably shouldn't be that way. Was that the first time you used the blinkers and hit the brake lights at the same time? If so then it may have always been that way.

    your brake and turn signal are the same bulb, it's a speacial bulb, newer cars have the brake and turn signals sseperate, yours does not. I belive it's called a single filament bulb?

    I understand the whole single vs dual filament bulb. The brake and turn signal operate off of the same bulb (1157, dual filament) this is where i am having the problem. There was no wire modifications and i have already changed both bulbs thinking that this may have something to do with it, but it did not change.The turn signals work fine, but stop blinking once the brake pedal is applied. I am not sure if this would have something to do with the brake switch or maybe the pigtail in the taillight.

    you have a light not working(or shorting) somewhere, check grounds(for rusty contacts), bulbs, on all four corners, most likely the back though. This is common on tailights that aren't equiped with a dedicated brake light(bulb) in addition to a dual purpose bulb.

    Also make sure the filaments in the bulb aren't touching each other--I've seen many that are,and it causes all kinds of weird feedback problems--a weak OEM flasher can do this too,and the grounds and sockets as the other posters reccomended.Good luck--been there,wiring dilemas always suck!. /forums/images/graemlins/frown.gif P.S.--its normal for the hazards to stop blinking when brakes are applied,but the directionals should be unnaffected,if they dont keep blinking something is wrong. /forums/images/graemlins/confused.gif)
