If you have a wheel puller(steering wheel) then the rest is easy. If you don't it's best to grab a repair manual because there are certain little tricks that should be known before attemting to do this.

Could be a bad heater core, any fluid leaking around it...check under the carpet and padding if you don't see anything under it on the ground. Your coolant may also be low, and it isn't circulating to the heater core, or a vacuum line may be off the hot/cold gate on the heater box, there are a lot of possible causes, but i would check for leaks and fluid level first
