during cold morning sometimes the sound system of my honda pilot 06 model doesnt work what's the cause?

Answer 1

There's typically a delay in the amplifier in the radio or separate amplifier, if it has one, while the circuits are warming up.

This delay feature is a switch of sorts that does not allow power to the speakers until the specified time has passed. A couple of seconds in most cases.

In your case, I assume this is an instant on radio with no delay built in. This leaves the possibility of the relay that is incorporated into the interior lights and the radio. This relay is also like a timed switch and it will, for example allow the radio to stay on for ten minutes unless the door is opened and then the radio goes off.

On cold days this relay might "stick" in the open position as if you had left the radio on and opened the door and let the relay turn it off without pushing the on/off button.

So, try turning the radio off manually before leaving the car and then see if it comes on the next morning when you push the on/off button after you're in the car with the doors closed.

Hope this helps. Might just need to replace this relay or do what works and save a few dollars.

Good Luck!

The cold slows down electrons so your electronics will not perform well at low temperatures. Thats why your car turns over sluggishly in the cold.
