Will a clogged air filter cause your car not to heat up?

it will cause your engine not to run, which would never produce heat.
If your engine runs, it may be low on coolant, have frozen plumbing, a bad water pump, a leaky hose, a bad thermostat, or a clogged something. Diagnosing the symptom before buying parts pays off every time.

No heat

If you have no heat in your vehicle then it is probably the heater core which is just a small radiator that sits behind the glove box. The thermostat itself is probably located where your top radiator hose connects to your engine. It is an easy and cheap fix, just pull the hose away after undoing the clamp and you should see it. If it is not there, then it will be in the bottom hose. Hope that helps you out.
