Any fuse that blows immediately indicates a direct short to ground...either in the harness or in a related component. Power from the fuse is being sent to the car's ground system instead of to the load it was intended to power. This will take a good wiring diagram and a voltmeter or test light to locate.
First, check for the recall on the blower resistor at recalls.gov or something like that. Second, check the fuse box located below the steering wheel.
run a hot wire directly to the blower motor. see if it runs that way.
check for water in the head light glass it could splash on the hot bulb and blow it.
Mercury did not blow up.
Check your thermostat. Looks like it is stuck open and needs replacing. That could be why your engine is running cold. Atleast its not stuck in the closed position.
There is 2 possible problems -# 1 your a/c system is over charged . # 2 The temperature control valve is not working properly
I have a mercury cougar and the biggest problem with every one that I have owned are their struts.3.8 Overheat and blow head gasketsANSWEREarly 90's common problems are electrical, normally interior. Otherwise there are generally no mechanical issues unassociated with the owner. If the 3.8 is overheating and blowing head gaskets there is a huge problem with the driver. My Cougar has 300,000 original miles on the engine and transmission.
you would have to see a mechanic about that problem
Are you sure it's the proper headlight for the car? Occasionally, installing a halogen bulb as a replacement (when the original was non-halogen) will cause the fuse to blow.
No, nothing happened to Mercury. It still exists.
you might need to refill the freeon
You might need freon
