I found this info for horn relay. If more than one relay, hopefully you can see wiring colors at relay, then look at horn relay wiring diagram and match the wire colors to the relay. I'd check applicable fuses first. Any electrical circuit needs voltage and ground.

Fuel is metered to the injectors based on a signal from the Engine coolant sensor. When the sensor goes bad usually the engine is slow to start. turn off and it start as normal. A cold engine signal will cause a rich supply causing smoking and misfire when the engine is at operating temperature. The gauge may read right but that does not mean the sensor is sending the right signal to the computer.

PAG oil is best if its totally empty 40 ml will do

run the engine at fast idle run the ac in maximum cooling and after a few minutes check the sight glass if bubbles present in the sight glass there is insufficient amount of refrigerant you'll need to recharge freon and about 10 ml of refrigerant oil PAG is best.

check relay then starter.

Remove the return hose at the pump & add apiece of tubing & put into a bottle under carRemove the injector fuse & crank engine to flush out fluid until cleanJust as with brakes -- don't let the reservoir run dry

Sounds like your water-pump bearings are siezed. Check how many pulleys the belt goes around... the very bottom one will be the crankshaft. That'll be very stiff (normal)... but any others will be the alternator, the water-pump, or even the power-steering pump. These pulleys should turn freely by hand.

here is a picture of a ****** for it...maybe you can findhttp://images.canadianlisted.com/nlarge/1992-mazda-b2200-automatic-transmission-first-offer-takes-it_4471600.jpg

Look from the outside of the driver window and take down the vin number and give that info to the parts store clerk and it will give them all the info they need

in the radiator

I have gotten away with it with a 1992 Mustang. Some people will tell you that you have to replace the seals in the whole system but you may not need to worry about it for as long as you own the car. Just replace them if you need to down the road and save your money now.
There is a difference in the weight of the oil in the different types of refrigerant. The converted systems never seem to cool as well as the old refrigerant but once your car is cooled then it stays cool in most cases.
I had my Mustang for 5 years after the conversion and it worked up until the day I sold it. I live in FL

Your Protege has a dedicated fuse for the tailight circuit, as well as a relay. The fuse should be located in the passenger compartment fuse box, but it could be located in the main fuse box in the engine compartment drivers side inside fender area. It should be labeled TAILIGHT, and be 15A, or 20A. The relay is most likely in the main fuse box as well, but I can't tell from the attached drawing so you'll have to track it down if necessary.

I'm sure you speed sensor is gone bad. You need to replace it.
Please don't forget to rate me ..It will hep me

the extra fuel is "reserve" to get you to a fuel station... this is normal. If you were to run it completely out you will damage your fuel pump, fuel is used to cool the fuel pump. Soo... DON'T run it so low!

Could be the switch itself. Pretty easy to replace the whole turn signal switch. I've had the flashers go out also on mine, but mine ended up being the switch. I grabbed one from a recycling yard, cost me less than $20.

you will need a pressure tester for this. the instructions are in the box and very easy to understand. usually, you connect the pressure tester to the fuel line line by detaching the external fuel filter or maybe there is a point for testing the line close to the intake manifold. follow the fuel line from the tank under the car if you are not sure. it's the biggest one of the two generally

you can try a local tow company sometimes they have the tools required to remove it if not the dealer can remove it and supply a new key

If your highbeams are working fine, you must be referring to your low beams not working I would simply check the 2 bulbs and make sure the low beam filament is good, theres a strong possibility that your BOTH low beam filaments are bad and require replacement of both headlight bulbs to get them working again its a very simple repair.....
