The headlights moving up and down on their own is almost always related to dirty grounds on the circuit - specifically at a multi-pin connector located just under the brake booster. It's a white flat plastic rectangle with about 7 leads running into it and attached with a machine screw into the shelf area below the booster. Water can collect there causing corrosion. The connector can be opened up and the contacts cleaned. There's a good video on cleaning electrical connectors on YouTube

SOURCE: mazda mx5 1990

The thermostats on Mazdas are notorious for kicking out and causing the fans to either not initiate or go on without effective results. My Protege went through 3 before I got my Miata, and I learned how to change the thermostat when it went out the first time. Hopefully, there won't be a second time, but whenever the car overheats and I notice the fans don't come one, I always assume it's the thermostat, and that's always the cause. If you don't want to fix it yourself, take it to a dealer, they're very accustomed to changing thermostats in Mazdas, believe me.

Mazda mx5 1990 how to test crank angle sensor

The only test is to watch it on a live data scanner while the engine is cranked over, then compare it to the graphs in the factory service manual. Resistance testing doesn't work here.

I own a 1990 Mazda MX5 and the headlights need adjusting - how do you adjust them please. The housing is flush with the bonnet so no need to adjust this just the aim.

After taking off the covers which suround the head lamps. There are two screws 1 in the 6 0`clock position to adjust the up and down position and one in the 9 0`clock position to adjust side to side position

The bonnet on my mx5 is high on one side

Found the problem one of the bonnet hinges was beginning to seize up put loads of wd40 on it moved the bonnet up and down to ease the oil in. Then closed the bonnet and pused down on it where the hinge is so that it became level with the wings. I then just loosend the bonnet nuts slightly closed the bonnet and moved it into the best position carefully opend it and did up the nuts if the headlamps are still a bit low open the bonnet and just pull gently on the back of the head lamp and they wil come into place job done it looks great
