I think my car has a coolant leak. It's a 99 Monte Carlo and it was fine last winter. This summer the ac started having problems that it would blow warm air and we had it recharged and then refilled on top of that and it didn't hold. Now our heater is blowing cold air especially when you stop. We refilled the coolant once barely a week ago. What could be some of the problems? Are the AC and heat problems related?

my husband says it gets warm when you're driving and then when you stop at a light it blows cold air again. It really makes me mad as we only bought this car 11 months ago and it was fine last winter.

If you had to significantly refill the coolant, then I agree, you have a leak and it would certainly explain the lack of heat.
No coolant running through the heatercore = no heat.
A couple of more common issues on your car would be a lower intake gasket leak or waterpump, but wouldn't rule out simpler causes such as hoses, reservoir cap, radiator, etc.

This does sound like the thermostat is stuck open and the coolant is running through too fast to get hot. Just pop in a new thermostat (maybe a $10 project) and see if this helps.
The A/C is a different matter and you must have freon leak in either the condensor coil, evaporator coil, a hose or line or possibly the compressor. The condensor coil gets hit with a lot of road debris since it is in front of the radiator. They can inject some dye into the system and after it has been run for a few days (summer time) they will hold a black light on it and look for a leak.
Good Luck!

"Two Problems, Not Related"
Heater; Replace Thermostat! Remove Heater Hoses and through Return Hose "Back Flush" Heater Core (Remove "Hot Water Valve" in Heater Hose Before Back Flush!)
A/C; "Freon Leak!" Good A/C Shop for Repair and Recharge!"

Hi a great & FUN way to check if you have a coolent leak is to fill up the tank with coolent, and then run your heater on low for about an hour.
If it smells like "pot", than there is a coolant leak.
It will be a faint smell however that does work

HI
well for starters check your thermostat that is the main part that will regulate the tempeture and that is how both the heater and air conditionor work. As for the coolent use the one that is ready mixed Iknow peak is one if you use regular antifreeze then you need to use 1 to 1 which means one gal jug of anti freeze to one gal of water. I hope this helps you.

If this car has the 3.1 or 3.4 liter engine, chances are the intake manifold gasket is leaking. Check the dipstick for you engine oil to make sure there's no coolant in it. If there is, you will have to have this gasket replaced right away.

Check the thermostat and the heater core

no they are two completely seperate systems...
The car heater is a seperate issue
have the "thermosthat" checked ..if it is stuck open ..the engine cannot reach its working temperature. (it is a relatively cheap job to fit a new thermosthat)
