Car AC Repairs & Heater Repairs

In Iowa's climate, air conditioning and heat are important in your home. And your car's air conditioner and heater are necessities, too! There's nothing worse than getting into your car on a hot summer day and your air conditioner blower doesn't put out cold air. It's equally bad getting in your car on a cold winter night and your car heater doesn't blow out warm air! Having air conditioning and car heater problems are more than an annoyance, these problems can make driving your car miserable. If your air conditioning system or heater isn't working, it's important that you get them checked out and repaired.

When you bring your vehicle to Big Jim's Automotive, our experienced mechanics will get it back to a comfortable temperature. You'll have cold air and warm air again -- so you'll be comfortable all year round!

Here are some typical problems and issues with car ACs and car heaters:

Interior Fan Failure

The two systems that affect your car's interior temperature have different reasons they might fail. Your car's air conditioning system and heater share the same fan, so your heater or air conditioner may be working properly but the air isn't actually getting to the cabin. This might mean the fan is not working which could be due to a bad fuse or the switch. Our mechanic will examine your system and get air flowing again.

My Car's Heater Doesn't Work

Winter can be brutal in the Midwest, so you don't want to go long without your car heater working in your vehicle. There are a variety of reasons your heater might not work properly:

  • Clogged Heater Core
  • Broken Heater Core
  • Thermostat

What Is A Clogged Heater Core?

There is a piece connected to your radiator that creates heat in your cabin when it's cold out. Sometimes these small box-like parts can get clogged and malfunction. This can cause you to not get heat and can fog up your cabin. The good news is a clogged heater core can be flushed by a mechanic.

What Is A Broken Heater Core?

Sometimes the broken heater in a car goes beyond a simple clog, and the heater core may be cracked or blown altogether. Signs of this type of failure might be a strong sweet smell in the cabin or around your car from the radiator fluid leaking. You might also notice your engine overheats but the heat still doesn't work inside the car. If your heater core has cracked or is blown, it needs to be replaced by a professional mechanic.

Thermostat Problems

Near your engine is a thermostat that gauges the temperature of the engine to help determine when coolant is needed. When the engine gets hot, the thermostat signals a valve to open allowing coolant to flow. If the valve gets stuck open, your vehicle might not produce the heat needed to keep the cabin warm. If your engine is warm or hot but you can't get car's heater to work, this thermostat may be the problem.

Can't Get Cold Air?

If you don't have a working air conditioner on hot summer days it can make you miserable! When your air conditioner isn't putting out that ice-cold chill you're used to, you probably need an AC recharge. If the refrigerant is low, you might have a leak that should be repaired so your AC system doesn't get damaged.

As mechanics, we don't want our cars chilly in the winter or boiling hot in the summer, so we'll make sure your car isn't either. When you notice your vents and airflow and temperature aren't working properly, contact us to schedule an appointment to bring it on by.
