Q: heater core replacement on 2001 Mitsubishi Galant

My air conditioner leaks inside when it runs and from what I've read it is a heater core issue. I plan on getting a new car next summer so I don't want to make any repairs I don't have to. My question is, how critical is it to get this done? If I can put up with the leaks will I be ok? It has 132,000 miles and I only drive it to work basically which is about 25 miles a day

It sounds like your A/C drain hole is plugged up. This is common and can be cleared out fairly easily. There should be a drain hole under your car and it is most likely full of debris.
I agree, there's an L shaped plastic tube that comes out of the heater core parallel to the firewall and then turns 90 degrees towards the firewall about 3/4 inch in diameter. You can see it just above the gas pedal(looking from inside, under your steering column) at the 2 o'clock position. Drill a small hole in it and use a metal coat hanger to unplug it towards the firewall direction and then towards the heater core direction. Then use a small screw to screw into the hole you made to plug it up. This is a quick fix, an alternative to a 5 hour removing the whole interior and dash to get to the core. If the leaking fluid is green the heater core is bad, if it is clear, the liquid is from the ac condensation
My car does not blow hot air -- but the Blower works and the A/C does not leak...what should I look for???
