Two Reasons Why the HVAC in Your Vehicle Isn't Working Right

1. Low or Leaking Coolant

Whether the heater isn't warming the car up or the AC isn't blowing cold, low refrigerant/coolant levels (or a leak -- from, say, a defective heater core) might be why.

Try starting your engine; set the AC and fans to max/high, and listen for a click (the compressor clutch). Is the system running too fast? Coolant's probably low. Air conditioning not due for service anytime soon? A leak's more likely.

Is the heater not blowing warm? The heater core's the likelier problem; its hoses are probably leaking. You'll know this from a steamy or smoky interior, the smell of coolant in the car, and the engine overheating.

2. Damaged Heating and AC Parts

Here, the trouble could be anything -- the seals, for instance, or the fittings, the compressor hose manifolds, or even the hoses themselves. We're talking things as simple as the front seal and O-rings or the Schrader valves. That includes where condensation drains out the evaporator, too, not to mention the AC condenser. Inspect the whole system.

Is the cabin warmer than usual? If the AC sounds funny, and the clutch is stuck to boot, the AC compressor is probably bad. You'll know a bad clutch, however, from connecting a voltmeter and not reading any voltage. Other reasons the compressor might be faulty include low refrigerant pressure, a bad cycling switch, and a fuse that's just plain blown.

Is the HVAC warning light lit, though? Maybe frost is starting to build up, and the AC button's flashing? If the system's got discharge pressure issues, on top of that, the trouble's probably AC condenser failure. You'll know that from the vents not blowing cold air. If none's coming through them at all, however, the problem's more likely a defective blower motor. Other reasons the condenser might be bad include failed cooling fans and a simple clogged cabin air filter.

In short, replace anything leaking, faulty, worn-out, or failed, and use OEM parts for the job.

Why Buy OEM AC and Heating Parts, vs. Aftermarket?

They're manufacturer-quality -- meaning, guaranteed to not only fit right but also work better. The aftermarket can't say the same; some of its parts even void factory warranties.
