Hi All, As the weather is getting colder here (relatively), I have tried to use my rear window defroster on my 90. When I push the button, I hear a buzzing sound, but get no indication that it is working (dash light or clear window). Any suggestions what could be wrong? Is the buzzing normal? It has been a while since I used it last.

Thnaks for the help.

Or does anyone know if boring a throttle body on a Renix engine will help performance or hurt mileage? How much?

It really wont do a hell of alot till you match it with another mod or 2.One highflow exhaust 2 maybe a header,high power ignition,etc.Hp with all maybe 10-12 if lucky. mpg abit better also.

I have a high flow exhaust and am looking at better ignition.

Any ideas out there on the defroster issue?

Thanks, David
