Before I start ripping apart the dashboard, I'd like to get some feedback for these noise issues in my 145k mile 2003 RX300. They appear to be originating (i think) from within the dashboard. The first, which has been going on for over a year is an intermittent clicking noise that can be heard regardless of whether the engine is running or not. It doesn't last long after the engine is off, but can still be heard for a few minutes. The second noise which began on 6/8/11, is a farting sound, also intermittent, but sometimes lasts for 10 seconds at a time. It stops completely when the engine is off. Sounds like it may be some type of vacuum hose issue, but I'd like an opinion. Thanks.
