I gotta heater problem, it's cold!
 

Any body had a problem with their heater blowing cold air while you are stopped, but then warming up again once you start driving. I've tried to idle high while at stop lights, and still blows cold.

Also, I can't get my e-brake light to go off.

Check your coolant level, it's probably low, so when you stop and the RPM's go down, the fluid doesn't circulate as much.

Where do you live? Check your radiator fluid. IF you live in cold weather, make a 50/50 solution radiator fluid, and distilled water. If you live where it is very cold sometimes the back brake will stick to the rotor and e-brake light might stay on. It is probally not releasing all the way. You might want to get it checked out.

man my a/c blows hot [not that it matters now, but still]. thinkin its the freon, but what else could it be?

Could be that's it low on R-134 (actually freon is R-12, no longer used but I call it that too) or it could be the A/C condenser is shot.

Most likely it's the refrigerant, just have a shop check it for leaks and re-fill the system. Probably like $100 bucks or you can get a $30 kit from AutoZone and DIY.
