Since having the Altenator belt snap last week I've been experienceing some problems with the headlamps. (Luckily as I was pulling into the drive way!)
Snicking noise coming from the dash (Probably the relays in the activating switch) and a what sounds like a buzzer starting to wail coming from under the glove box. The lights flicker then die (although the side lights remain lit up, I did not check the rears, but presume they too are working) At this stage the head lamps remain in the up position, and will not raise or lower on the light switch, but can be lowered using the manual/lamp washer switch.
Left them 30 seconds and tried them again, and everythnig worked fine.
Now, I know the control relay for the headlamp motor is under the glove box, mounted on a chassis plate so I will check this first. (My theory being a damaged wire >many thanks to the previous owner for causing me so much grief< is now earthing when things heat up, thusly causing the relay to be switched/overheat this is in turn leading to the relay in the dash being repeatedly switched giving the clicking sound)
The real puzzler is what the hell is doing the buzzing? The main warning buzzer is in the instrument surround, so I know its not that. The Mazda Alarm system is located in the area around the glove box/footwell/airvent section, but I never saw any kind of speaker/buzzer attatched to its myriad of control boxes.
If anyone as any advice/comments/mockery then please, lets hear it! :)
BTW, for those who dont know its a 1991 Turbo II.
