Don’t worry, you’re not alone in this frustration. Picture this: you’re cruising down the road, enjoying the breeze, and then bam! The cool air bids farewell, leaving you in a sweat-inducing predicament.

Check the Battery Connections

When facing issues with your car’s AC after a battery change in your Azera, checking the battery connections is essential. Loose or incorrectly connected terminals could be causing the problem. Here’s what you can do:

  • Clean any corrosion or debris on the terminals to improve connectivity.
  • If you spot any frayed wires, replace them promptly.

Properly maintained battery connections can often resolve AC issues post a battery replacement.

Inspect the Fuse Box

When facing car AC issues post a battery change, checking the fuse box is crucial. Here’s how to do it effectively:

  • Start by locating the fuse box in your Azera. It’s commonly found near the driver’s side dashboard or in the engine compartment.
  • Inspect the AC-related fuses in the box. Look for any signs of damage like a broken filament or discoloration.
  • If you find a damaged fuse, replace it with one of the same amperage. Mismatched fuses can cause electrical problems.
  • Ensure all fuses are properly seated in their slots. A loose fuse can lead to electrical issues.
  • After checking and replacing fuses, test your AC to see if the issue has been resolved.
