ISSUE 1: My oil pressure gauge has started periodically bottoming out. I'll get the "check gauges" alert and then it will return to normal pressure. Sometimes it won't bottom out, but will suddenly dip very low and immediately jump back up to normal when I hit the gas. This usually happens when idling but not exclusively. Is this a real problem or a gauge issue? I know there's been an ongoing issue with many Bonneville owners where the oil gauge will stick at 120psi, but this issue is different.
ISSUE 2: My blower motor (for AC) has a bad vibration. How do I access the motor to see if there may be leaves or debris stuck in it?
