Why is my 2003 Silverado not getting heat?

Either coolant is not flowing through the heater core or the hot/cold blend door is not working. First check the level of coolant in the radiator after the engine cools down. If ok, start the engine and let it get warm, then grab both heater hoses where they go into the firewall to the heater core.

Why is my car AC not working in the heat?

Your Compressor Might Be Broken, or Its Clutch Isn’t Engaging. If refrigerant is the lifeblood of your A/C system, the compressor is the heart since its job is to circulate refrigerant through the system. Overheating, lack of lubrication, and low refrigerant levels are all common causes of compressor failure.

Why is my Chevy AC not blowing cold air?

Your car’s AC not working is most likely caused by a freon leak or a failing compressor.

Why is my Chevy Cruze not blowing hot air?

A bad heater core is a very common reason for this problem. You could also have no or very little coolant, although that would lead to overheating and a few warning lights coming on. If it isn’t blowing any air at all, hot or cold, you could be looking at an issue with the blower motor.

Why is my Chevy Uplander overheating?

The most common reasons a Chevrolet Uplander is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.

How do I fix my car heater not blowing hot air?

If the thermostat can’t signal to the car that the engine is warm, the coolant won’t be sent over to provide heat to your heater core and the air will stay cool. Thermostats are a relatively easy and inexpensive fix, so installing a new one can get your heater working again quickly.

Why is my car blowing air but no heat?

Low coolant: Whether caused by a leak or water evaporation, low coolant is the most common source of poor heater output. Thermostat: A stuck-open thermostat prevents the engine (and coolant) from heating up. Heater core: A clogged heater core restricts coolant flow, giving up little or no heat.

Why is my engine temp high but no heat?

The problem you are going to run into is that the temperature gauge is designed to read liquid (coolant) temperature and not air temperature. The fact that it is not getting heat is likely because it is low on coolant and if it is showing overheating on the gauge with low coolant it is VERY hot.

Why is my AC not working in my 2007 Chevy Uplander?

The most common reasons a Chevrolet Uplander ac isn’t working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor.

Is my car overheating or is my thermostat bad?

If it continues to read too cold or registers too hot, then there is the chance that the temperature gauge should be replaced. If working correctly and your vehicle keeps overheating, then there may be an issue with the coolant or engine itself. If too cold, then the thermostat could be stuck open, causing overcooling.
