Your auto radio is one of the most essential components of the vehicle. In addition to providing entertainment, the radio offers other conveniences, such as communication and navigation. So, when it doesn’t work, your driving experience is greatly affected.

Water damage on car radios may be the worst problem to deal with. In most cases, replacing the various parts is usually the solution. But we hope yours doesn’t get there, and that with the help of this guide, you’ll be able to fix it. But before we offer our possible solution to “my stereo receiver got wet,” ensure you have these tools:

  • Pliers or a wrench
  • A clean, dry microfiber cloth/towel
  • A hair dryer/blow-dryer
  • Fuse puller (you may find one inside the fuse box cover)/a small set of pliers
  • Voltmeter

1.Check if the Fuse Is Blown

If water comes into contact with the electronics, it can trigger several issues. The most common car electrical problems after rain are short-circuiting, which can blow a fuse. So, the first thing you must do when your radio gets wet is to examine the fuse.

The fuse may be on the back of your car stereo, but you can consult the owner’s manual for the exact location. Once you find the blade fuse, pull it out using a fuse puller or a small set of pliers and look for the fuse wire.

Check if there’s a visible gap. Other signs of a blown fuse include a dark or metallic smear in the glass. If the fuse is damaged, replace it with a new one. But if it’s intact, put it back and go to step 2 below.

.Disconnect the Battery and Remove the Waterlogged Parts

You must remove the battery before working on the wet radio. Disconnecting the battery will prevent any further damage to your radio. The battery is usually located in the engine bay on most vehicles. Check your owner’s manual for the exact location.
You’ll need a wrench or pliers to loosen the nuts holding the battery’s terminals. You don’t need to remove both terminals. Just pull out the negative terminal. Next, examine the stereo for any signs of flood damage and remove the soaked parts if possible. That may include the wires, speakers, and other components.

If you cannot remove any part of the radio, reconnect the battery and try to run the car’s AC for a while. Hopefully, the heat produced will dry the moisture behind radio screen and other parts. After that, skip to step 5 below.

3.Dry the Wet Parts

Grab the dry, soft cloth and gently dry the wet parts individually. It would be best to detach each component before drying for better drying without causing harm. Alternatively, you can dry the wet radio parts by blowing hot air. A hairdryer is the best tool to help with that.

Dry the Wet Parts

It would be best if you detached the speakers from their position and gently mop the water out using a soft cloth. Focus on the cone, magnets, and terminals. They are the most sensitive parts; even little water can wreak havoc on them. That’s why many people find that car speakers not working after rain.

You might need to cut some patches from a paper towel to use as patches to cover cracked areas of the speaker’s cone. Use glue to coat the areas around cracks on the bottom and top ends. Also, coat one face of the patches and gently press them over the cracks. Leave your speaker and other components to dry in a well-ventilated spot.

What would you do if the car touch screen got wet? You’ll also need to detach the screen, blow-dry it, and then keep it in a container of rise for at least 24 hours. Rice is an economical and effective way to drain moisture from touchscreens. So, if your Jeep screen got wet, just bury it inside a container of rice to extract the water.

4.Replace the Irreparable Parts

Depending on the extent of the damage, some parts, especially the speakers and wiring harnesses, could be damaged beyond repairs. It would be best if you replaced them. At this point, you’ll have to spend some money. Once you’ve replaced the parts, reassemble the radio.

Before assembling the parts, ensure the car battery is in good condition. You can use a voltmeter to determine if it’s outputting the right voltage (at least 12.4V).

5.Test Your Radio

After reassembling the radio components, you’ll need to test them. So, turn the radio on and see if it works. If it’s working, congratulations, you’ve fixed it. If, unfortunately, not working, you’ll most likely need to buy a new radio or stereo. You can consult a professional for advice before making the bold move.
