Could be something as simple as a bad thermostat or low on cooling fluid or maybe a problem with the water pump.

Winter's coming. Get it fixed.

Make sure the thermostat is not stuck closed or open.Vehicle will never warm up properly if its stuck open. If stuck closed, engine would probably be overheating. He next thing I would do is remove the heater hoses from the heater core tubes at the firewall. After removal, use a hose pipe to flush out the heater core.Spray through the larger tube first then spray through the smaller tube last. If you begin to see rusty or dirty colored water coming out of the core tubes, that's a sign of a clogged or partially clogged heater core and that will definitely cause the heat to be non functional. If it is dirty, I would do a complete flush of the whole cooling system. If that's more than you wanna deal with, at least flush the heater hoses and/or pipes out that run from the water pump and thermostat housing up to the heater core tubes. If the heater core isn't clogged, the blend door fuse/relay should be checked. If its good, check to make sure the actuator is working ok. This part moves when you adjust temp

I would first flush your heater coil, if you don't know how look it up on youtube. If that doesn't work then it will get price, i've done this before and i was up and running in 30 minutes.
