Question about 1996 Mercury Grand Marquis
I have been putting some work into my Marquis coolant, sparkplugs, and oil to name a few just got it to drop the check engine light (YES). All I need now is to figure out why my A/C after about 10 mins or so on the road it releases a gas or burnt nail polish smell cant put my finger on it exactly. looked for leaks couldn't notice anything does any one have any idea as to my first step to remedy this problem? please let me know so I can have my baby driving sweet again thanks.
Does the smell happen if you are running the hvac on just vent ?
The ac itself would not cause a smell unless the clutch on the compressor were slipping and you would probably hear that.
Its a sealed system just like your fridge at home.
So it could be something in the engine compartment that is coming thru the vent when the ac is on. The most common smell is a musty or mold smell from moisture inside the hvac.

1 minute won't reset any codes for the Grand Marquis. You need to dicsonnect the ground and wait 15 mins for the caps in the comp to fully discharge.

Go to an Autozone or Oreillys for a free engine scan. This will help you find the problem.
You could have an intake gasket or head gasket leaking into a cylinder. The scanner will show if a cylinder is misfiring and which cylinder it is. You can also get a loaner tool such as a Radiator pressure tester which can pressurize the system without the engine running. In some cases, antifreeze can evaporate or run off while the car is in motion.
Once you repair the part use some household detergent and hot water and clean the area you repaired. The smell from antifreeze will linger for months if you do not remove it. Also after you repair the problem, use the pressure tester again to insure the repair is holding.

SOURCE: 2002 Mercury Grand Marquis hood
take a close look at the male part of your hood latch. should be a heavy spring on it which pops the hood up a bit to allow you to get your fingers in to fully release it. could be missing or bent. You can buy another at a junkyard, most likely any from a full size ford or mercury 95-05 will work. either that or the female release part is stuck and needs some grease.

You work on Check Light issues first,so check
for codes & proceed from there.
Need some knowledge or a trouble chart,as codes
don't tell you what is wrong or what to replace

might be the oil filter adapter (the stud that the filter threads onto). I would try replacing filter first twist on till tight then use filter wrench to tighten 1/4 to 1/2 turn more
