Okay so I've looked up and looked up and I can't find anything. Everyone hears a noise from there passenger but there is a tapping noise coming from under my steering wheel. It's only sounds when I have it on "on" (not cranked) and when the engine is running. 2003 gs 300 with 142,000 miles. Please help thanks a lot in advance

 

I can hear the sound clearly at the pedals

 

Don't mean to be simplistic, but had the same kind of tapping. Turned out to be the keys hitting the dash.

 

Thanks lol I had that with my last car and I know that's not the problem now because I have the key by itself. Thanks I appreciate it

 

Is it a continuous tapping?

Check and make sure your foglights aren't blinking on and off rapidly.

Sounds silly...but when that happens the relay taps continuously

 

I'll check tommorw. And yes it's a continuous. The only time it stops is when the key isint on "on"

 

Can you distinguish the noise from your brake booster cycling?

 

I think the noise might have something to do with ac because today while driving it wouldent blow air
