Electrical problem..no turn signals hazard sw stays on when pressed

I have a 325e 1987 e30, problem....no turn signals, swaped hazard sw, cleaned all bulbs and sockets grounds, battery terms, and cables, even cable to body from - side of battery, ckd flasher....can anyone give me the next step to take, thought I covered them all removing the dash is next if all else fails....thank you for your help.

take one of the bulbs out and test light and dvom to see how much volts you're getting

I will give that a try....thanks

do the lights come on and not flash, or they dont come on completely

The hazard light switch comes on when ignition is on when depressed, no flashing.....i have parking, brake, reverse lights, all working. But no flashing turn signals on dash, in front or in back of car. I've checked & cleaned all bulbs ,sockets & grounds.

Does it make any signs or noises at all when you hit the switch? Check the fuses and i've heard theres a plug up behind the front bumper that causes some problems with the signals

The hazard switch clicks when you press it, but thats it, there is no other sound or signs made or noticed.

And I have ckd fuses twice

Make sure you have the right bulbs up front, ive seen a car with the wrong bulbs cause crazy things to happen. If all are the correct bulbs than get a test light and start at the switch checking for power as you go...do one side at a time. I have also bought new flashers that were bad.

I will do that...i just bought another turn signal with relay attached just incase.

You replaced the flasher inside the steering column? How about the hazard switch?

he said he checked it. and ive been trying to figure how you check a flasher.

it sounds like the flasher is bad. if the lights work and dont flash, that resorts back to the flasher.

I will ck the hazard sw in my other e30 (little red devil)....i have 3 or 4 sw's I will try them all, hope to fix soon, going to bimmerfest on the 19th in cali, gotta do some work on the little red devil to....

+1 It's a common issue in a 25 yo car bro. I have had to replace 2 of my 8 E30's flashers.

I don't recall say that I checked the flasher, but I have tried another flasher and that didn't work. when I figure out how to check a flasher I will be sure to post it for you.

thanks for all the input everyone I appreciate it. I will apply all advice in the am. thanks again, if you think of anything else please post it.

right there in the bold.

maybe the switch itself is bad

Your RIGHT, should have been CHANGED flasher.....i stand corrected. Thank you.

Ok, now I have checked every bulb,socket,ground,fuse, got battery car charged,replaced all under the hood relays, checked & cleaned the 2 fueses next to the fuse box, I did find one bad wire turn signal ground, repaired it. All lights WORK,except blinkers, I.installed a headlight switch, different turn signal arm with relay, ohm'd & test light everything the looked like it had power to it. The only thing I have found is the BLUE wire with a RED stripe on the turn signal pins under the steering wheel is DIM,when I test light it, looks like the wire diagram traces it back to the cluster, "not to sure how to read to tho", so I removed the cluster, looked at board, "see pic" , I have another, to put in & see what happens. Anyone have ANY OTHER ideas to what it might be....please, i've just about tore the whole car apart.

Look at the main board for a crack around the circuit that goes over the top of the screw hole on the upper left area., check the other side too. Scrape off paint, solder and paint back over with polish or paint pen. I had an E30 that only the left cluster blinker light wouldn't flash but the lights outside did, was a broken circuit where I mentioned, and I noticed I wasn't the first one to have it happen either when I posted my results years ago.

Will look, thanks

hey im new to this forum and im having kinda the same problem, my turn signals and hazards do not work, i press the hazard button and the red light comes on but i dont hear the normal clicking and the lights dont come on, iv checked everything besides the actual button that you press but since it lights up im assuming that it works. now my turn signals also dont work, when it was first starting to go bad i would signal left and i would hear click click then nothing then a couple seconds later click click then i would turn it off. when it doesnt click the turn signal doesnt light up but when it does the turn signal lights up. one day i was in traffic and having a bad day, i was trying to switch lanes and i didnt hear the noise when you use a turn signal so i hit my steering wheel and it starting to click and the turn signals worked then stoped again. now no matter what it doesnt work. can anyone help me or is it the same problem littlereddevil is having?

Disconnect your pin connector that leads to the turn signal...use your test light and test the blue w/ red stripe wire...see if its bright or dim, try it with ignition off, on ..also with lights off, on....mine is dim.

Well no luck in finding the problem or why the blue wire w/ red stripe has low "dim test light bulb" power. Im gonna take her to (certified auto electric) and see if they can track it down. Thanks everyone. Time for bimmerfest 2012 ...pasadena ca. Im taking "RED"

Anyone going from tucson az?
