Radio Static

[Rickb1b]

Ok guys getting ready for winter I decided to update my heater blower motor with the Chevy mod.

Now when I turn on the heater motor I get massive static through the radio. Anyone have any ideas for eliminating this static.

Make sure you have a clean ground.
Then make sure your power wire is not shared with a bunch of other wires
Also make sure your speaker wires are not near the blower wires

1-turn off the heator
2-put a CD in
3-turn the XM on instead
4-turn off the radio

Just being a smartass. Im always dealing with this and CB radios. Does your radio have a noise filter?

Also move the ground for the radio or blower motor if they are on the same one there tends to be feed back. One other thing that may be done is install a noise filter on the radio. Another option is you can install a 0.5 uF bypass capacitor between the heater motor and ground. most parts stores or radio shack should have these.
