I never had static in my Bose sound system. I bought a bug guard and installed it, I now get static in the sound system. Even with the system off, the static still comes through the speakers. Remove the bug guard, static goes away. What would cause this. Thanks.....

2004 Chevrolet Silverado 1500 Question: Static from Bug guard, only happens when the bug guard is installed

No way! Has to be just ram air noise, vibration, from the bug shield. Does it do this when sitting still????

I promise you it is neither ram air or vibration noise from the bug guard. I have used a stethoscope to listen to the speakers when driving, the noise is in the speakers and starts around 35/40 mph. I had it to the dealer and they removed the guard and the noise stopped. I drove for months w/o the guard and had no issues, reinstalled it again and on the way to work the static started again. I took it off again and the static is gone. Even with the radio off the static would still come through the speakers. The dealer had no answers other then to leave the guard off.

This has everyone baffled, I even rode in the back seat while my wife drove just to reconfirm it was coming from all of the speakers. It was and with the sound system turned off. I was wondering if the static produced by the airflow passing over the bug guard could be coming through the antenna? Maybe a bad antenna? The Dealer said no problem with the antenna. I've owned many vehicles with bug guards, this is a first. I took it off and the static is gone.....Now my damn fuel gauge broke, what next. 41000 miles and it's falling apart.

Hell, i give up on the bug shield!! However the fuel gauge is another matter. I hope it is the tank module because if it is the dash cluster it has to installed by a GM dealer due to programming! A 'real' scanner can sweep gauges to see which dont work. Get this test performed. Good vehicle though,dont know of a better truck really. All of them regardless of make give trouble! Now if you ever figure out the bug thing please let me know.

The bug shield is a mystery, I have friends with the same truck and they all have shields yet I'm the only one with the static issue. As far as the gauge, is the tank module in the tank? Not sure how to test that? I did test the power going to the sending unit and it is powered up to the unit. I unplugged the unit and used a test lite to see if the gauge would move and it didn't. I found a company online that will rebuild the cluster, new step up motors, gauges lights and mother board and guarantee it for life. They said it wouldn't need re-programing just remove it send it and reinstall it after the rebuild.

Cool, the reason is it is still the OE cluster! Pump/gauge module is in the tank. If you can ground the gauge wire at the sender connector fuel reading should go to full, dont have access to schematic here but can be found to see what color wire, i THINK purple. If you ground the right wire and gauge doesn't go to full it is the cluster OR least likely a broken wire. I know of one instance a friend bought a reman from a dealer, istalled it and worked for 15 miles, locked up, dealer then told him why!! No s..t! Oh, if gauge does go to full it is the pump module! Remove bed to replace it. YES move the bed rearward to gain acess to module just behind cab. Youtube. IF it turns out to be the module.

Thanks for all the support. It is well appreciated. I disconnected the plug going to the sending unit and tested each wire in the plug( grounded each wire) the gauge never moved from empty. On the re-manufactured cluster, They will remove and replace my old step up motors and replace the gauges and the board and back it up for life of vehicle. They are telling me that it does not have to be reprogrammed because they are using my original cluster? The mileage will not change either. They said to remove the old cluster, send it to them, they will recondition and return it. I replace it in the dash and away I go? Lots of good feed back on the site, I know anyone can post good remarks but sounds legit......Again, Thanks for the support, I'm not a mechanic but do little things on my own.
