Question about 1991 Mercury Grand Marquis
Water on the back floor passage side and little damp in front end.
a man said my heating coil could be broken.
also, the air bag light keeps blinking while driving the car.
First you need to get a flash light go to your pass side look arond the black casing off your heater see if the bottom is wet try with heater on and off usaully when a core is given that much water out when you turn your heater on it will steam your window and you will smell antifreeze if theres any if none of things are present i would check the seal around your windshield around firewall area rain can get into areas that the factory seal might have dried and cracked open leaving you with a wet carpet and a puddle in the back floor pan as for the airbag light you need to have the light reset at a garage could be a stored code in computors memory you can try your self by taking the fuse that says ecm leave out for ten seconds start vehicle see if it reset second way take pos cable off your battery leave off 10 15 seconds reinstall start if light stays out great if not you will need to have reset with scanner like a snapon or rotunda
