Why is a 98 f150 leaking coolant near firewall?
If its inside the cab at the firewall, its probably your heater core which is located on the passenger side under the dash. This repair is usually not much fun. If its leaking in the engine compartment near the firewall, its probably a heater hose that is failing. This is an easy repair

How do you keep the air conditioner from leaking inside the front passenger floor board of a 1998 jeep grand Cherokee Laredo?
If you are sure it is water and not coolant, then the A/C Condenser drain line is stopped up. You will find it near the firewall on the passenger side. Look for a tube under the Jeep. If it is coolant, which will taste sweet, your heater core is leaking and must be replaced.
Water leaks through a hose in the firewall?
Your heater core, which is under the dash is supplied by coolant from the engine. If it is leaking, or the hoses to it are leaking, it could end up on your carpet. Also, if the drain for the A/C evaporator is clogged, you would have a similar result. This sometimes happens after getting a car undercoated.

How do you now when a heater core is bad?
Heater core will usually leak. Check the floor under the dash & near the firewall. You will smell anti-freeze/ coolant inside your truck/car. Inside windshield will fog up & there will be an oily film on the glass. On some cars there is a drain tube that goes out thru the firewall to keep the coolant from leaking inside ( 95 Gran AM GT for one) Look for that tube near the heater hoses at the firewall in the engine compartment but make sure the coolant is coming from the drain hose & not the heater hoses
1995 Sunfire coolant is leaking from area located under steering column have already replaced thermostat and coolant in reservoir tank is full also noticed coolant smell in interior of car when heaton?
If you are getting coolant inside the car your Heater core is leaking but if only smelling coolent. The hose on the exterior maybe the issue and it maybe that the sound blanket in that area where the ends of the heater core pass thru the firewall is asborbing coolent hence the smell. This should give you a starting point hope it helps.
