AC duct rattle
Thanks for all your info reg. the caddies, very helpful and interesting discussions here.
Just got a 91 DeVille, Touring. Got it from a friend and it's in pretty good condition with 82k miles.
I spent some money already doing tune-ups, trans oil change, wheel bal., and had to replace the dist. cap and wires ($500 total)
There is a persistent buzzing vibration at iddle that I found out was the AC duct (looks like the AC duct), and apparently the engineers at GM knew about this because there is already a cushioned bracket that connects it to the front fender.
The vibration gets better with the AC off, but it's still there.
Does anyone know about this problem?
I appreciate your help with the info.
