Question about 1989 Ford Bronco II
SOURCE: A/C Stopped Blowing Cold Air
Hmm, lets start outside. On the unit sitting out there you have aside
from the electrical hookup, two pipes. One large and one small leading
from that unit into the house. The large should feel cold and the fan
on the unit when it's running should be blowing hot air after being on
for a shake or two. If you see ice collecting around the base of the
hookups, you could have frozen valves from lack of air flow over the
coils inside the house. Too high a charge might do this too but it's
not likely. If it's frozen you'll have to let the system defrost for
some time (by turning it off) after the flow is restored.
Now check the air filter. Sometimes the Hepa filters get so full that they are restrictive in air flow after even a short time. It's better to change out the cheaper ones alot than crimp the flow.
Now if you got air flow to that and it's not coming out of your vents, you may have to open up the plenum to clean the coil inside. I shouldn't need to tell you to be careful and not cut the lines and have a idea of what you are going to patch any holes up with after you make an inspection or service port there (cause I just did). Sheet metal work goes for about $300.00 if somebody else does it. If this is clogged up, you will be experiencing short cycles on your heat as well cause this will build up heat which will make your burner shut off prematurely till it cools and then it will go back and forth in this way never really allowing the blower that puts air across the heat exchanger (and in this case coils) to take a break. It will seem like it's on all the time.
Now comes the disclaimer: If it's above your level of experience, expertise or ability, call in a professional! Messing up can get expensive and dangerous! While extensive in explanation, there's some things that would be common sense to me like when to use the fuse link outside or the power switch mounted on the side of the furnace. But I've have had my hands on wires that run over 300 volts total. Some things you only touch once! Be honest with yourself and I hope you're chillin out soon.

It is likely a simple flasher causing your problems. Try locating it under your dash board and swapping it with the hazard flasher for a quick check. They sell for a few bucks at the parts store.

you will have to take it to the dealer and have them plug it in the computer to see what code it spit out that way they can narrow it down the problems; it can get expensive by replacing parts and hopping it will rectified the issue. The service engine light telling computer the engine is not running properly and needing attention. any time service engine light come on it will have some impact on your gas mileage and some performance however it may not have any effect to your engine running. keep in mind computer only program to sense the engine running at 100% optimum and anything less the computer will trigger the service engine light. it will cost somewhere around 75-80 bucks to have them run the test, trust me its worth every penny if you calculate the loss of your mileage over time by doing nothing or keep replacing part that need not to be replace.
