I had 2 problems and fixed one but the other still exists. When my head lites are working, all is fine, but when the head lites go out by themselves, the parking lites are still on, the high beam indicator is on for both high and low beams and the windshield wipers come on without being turned on. when the head lites come back on by themselves, the wipers stop and all is normal.
I have checked all fuses and do not find a relay for the head lites. I have banged on the fuse box and tapped hard on the wiring coming from the head lites including the main harness. I banged on the head lite switch and ignition switch and nothing seems loose. no wires seem to be loose or plugs to wires everywhere don't appear to be corroded. I banged on bodyparts under the hood, but nothing points to an answer. the lites don't stay on very long before they go out for no reason.
My next step will be to look for ground wires to see if they are corroded or barely hanging on, but the visible ones didn't react when I banged on them hard.
Please let me know what you think. Thanks, Mr. B

Your light switch may be defective. These switches have internal sliding contacts and they can malfunction internally without any visible loose wires or corrosion.

As stated in my question posted, I was going to investigate the grounds to the headlights. At first I hooked a ground to one of the two thick wires and the headlights came on. Not going any farther for that evening, I just made it a temporary connection. Turned out to be the pos wire to the high beam. I had to make sure not to put the high beams on while driving. Later I went to an auto parts store and they had a manual on my year Mazda, so I looked up the wiring diagram for the headlights and found out that one of the thinner wires, the black with yellow tracer, was the ground for both beams. Being surprised that such a thin wire was the actual ground, I moved the ground wire to the black with yellow tracer and now have everything back to normal. Somewhere there is a plug that takes that black with yellow tracer to ground, but I didn't figure out where. Guess I'll just be happy to have headlights now and will consider that the switch you refer to, is where the ground originates from.
Thank you for the info. My car runs great now and I will be taking it on a long distance trip to Miami soon. I will have a better chance to look everything over real good in the better climate.
Thanks again for your help. Sincerely, William Lichvarcik Sr. 216-240-2000

I went to advanced auto parts and looked in the book for MAZDA 626 and looked up the ground wire colors in the headlight area. Once i found the ground, I tapped into the ground anbd made another connection to ground on my own. I suggest that you find the ground side of whatever is not working properly and tap into it and touch ground with it and see if that fixes it. GOOD LUCK, Bill

Its been a long trouble free time since my last post here. My wifes 94 626 LXA ATX Air Bag started lighting up last month. It flashes then stops then flashes again. Never stays on solidly.
Car has 88K miles on it and is in Athens Greece.
I cleared the codes with the battery disconnect step on brake pedal for 10 seconds trick. This stopeed it from flashing for a day and I
Brought it to a Mazda guy who tried to run diagnostics on it and it showed no codes.
It was not flashing when I brought it, and now 2days leter its flashing like crazy. He asked me if the I4 is a FS V or FS1 I did not know the answer. The 93 is a Ford EEC IV ignition so I dont think he will ever get any codes.
Unless the airbags are different from the OBD 1 system the only way I ever got codes in 10 years is the OBD1 jumping wire technique, and reading check engine light pulses
Any ideas ?
Does anyone know what the 1993 626 LXA I 4 engine is . Here is Vin if that will help
He said when light flashes that means airbag will not open. I am afraid it will open when wife is driving it . Is he correct ?
My wifes uncle said that flashing light means a sevice reminder based on age/mileage and mazda can reset it . I thought the battery disconnect would do it but its back so is there any way to reset it , or is it defective for real

#27 of 31 Frustrating Electrical Problem
Nov 22, 2012 (7:59 am)
I got a 2000 626 lx 2.0 4 cylinder. Last week i was driving down the road and got a battery light on and when i looked under the hood I seen my wire from the positive to the fuse panel on the fire wall came loose and was almost out. I re attached the wire and drove to school that night and then all of a sudden coming home from school the light came on again and I was at about 45 mph coming down the road when i lost all power to my car I coasted to then nearest parking lot and seen the wire was still connected nice and tight. I was able to get the car jumped the next day to get the car home. I took out the alternator and had it tested and it came back as passing 3 times on a variable speed tester. I replaced the ground and positive battery cables in the process case there was a bad spot in the cables. My car is still not working and I checked the battery it is good also. Could the voltage regualtor in the Alternator be faulty? or do I have some other unforseen problem?

FIRST THING TO TRY IS PUT A HEAVY GROUND WIRE FROM THE ENGINE BLOCK TO THE VEHICLE BODY, FIRST. IF THAT DOESN'T FIX IT, THEN START PUTTING GROUNDS FROM EVERY DEVICE TO THE BODY. GO TO THE HEADLITE GROUND WIRE AT THE HEADLITE AND GROUND IT TO THE BODY, ETC FOR EVERY DEVICE TILL U FIND THE RIGHT ONE.
SORRY ABOUT THE WORK INVOLVED, BUT THAT IS WHAT IT TAKES TO FIX IT.
A QUICKER ANSWER IS TO SELL IT OFF. THAT IS WHAT I DID WITH MINE.
