If you’re having Jeep Grand Cherokee climate control problems, turning your climate control system off and back on might just do the trick. If not, the problem could be with your blend door actuator, blower motor, or A/C control module.

Resetting a Jeep Grand Cherokee’s climate system requires pressing the “browse enter” and “power” buttons.
If the problem persists after trying this electrical reset, there may be various underlying issues that a mechanic would need to address.

Jeep Grand Cherokee climate control reset instructions

Your Jeep Grand Cherokee now blowing cold air when you need it can be pretty frustrating.

Various issues that could cause this problem, but more often than not, it’s an electrical issue. And if that’s what’s causing your car to become a hot mess, you can fix it at home for free.

All you need to do is reset the electrical system. Here’s what you need to do:

Step one: At the same time, push the “browse enter” and “volume” buttons on your dashboard.

Step two: Press and hold the buttons until your dashboard screen turns black, then powers itself back on.

In those two easy steps, the climate control system should reset itself. But if that doesn't work, you’ll have to do a little more digging.

Other reasons your Jeep Grand Cherokee A/C isn’t working

Resetting the climate control system solves an electrical problem. But your car’s HVAC system is full of other components that could easily cause a climate control issue.

Blend door actuator malfunction

The blend door actuator, or HVAC actuator, is a tiny motor that controls the vents that direct airflow into your vehicle’s interior.

If your blend door actuator is malfunctioning, you’ll likely hear repeated clicking sounds from underneath the dashboard. And if the air is blowing cold on the passenger seat and hot on the driver’s seat, you’re probably dealing with a broken blend door actuator.

What to do: Unfortunately, this calls for replacement—not repair. If your blend door actuator is on the fry, you’ll need to purchase a new one.

Dirty air cabin filter

The air filter functions as a barrier between your HVAC system and your vehicle’s cabin. Over time, it can get clogged up with dirt and other engine debris that slow down airflow.

How to catch it: An increase in your engine’s fuel consumption also indicates that you’ve got a dirty or clogged-up air cabin filter, meaning it might be time for an

A/C blower motor failure

The blower motor powers the fan that pushes temperature-controlled air into the cabin through the dashboard vents. A

busted or worn-out blower motor

will make wheezing or clicking noises when you turn on your A/C.

Faulty cooling fan

The cooling fan blows air through the radiator to lower the coolant temperature and overall temperature of your engine.

If your cooling fan is on the fritz, you’ll notice that your A/C vents aren’t blowing enough air.

A/C control module failure

The A/C control module is another electrical component of your HVAC system that controls the heating and cooling functions.

You’ll know that there’s a problem with your A/C control module if your climate control system is on auto or manual control but no air flows through the vents.

Your car’s HVAC system is complex. You probably don’t think about it much, but there are a lot of different moving parts that help get cold air in your cabin.

Loose mounting bolts, a coolant leak, or any other dysfunction can create a major problem.

Because there are so many possible causes of your Jeep Grand Cherokee climate control problems, it can be hard to pinpoint the source. If you have an onboard diagnostics (OBD) scan tool, you can get a trouble code to help narrow it down.

The easiest way: If you don’t have an

OBD scanner

on hand, take your Jeep to a mechanic. They’ll diagnose the problem and give you an idea of what you can expect the repairs to cost.

It’s best to look for a mechanic who is certified to service HVAC systems since working with A/C refrigerant requires special expertise.
