Blazer Antenna and Remote Issues
Summary of the thread
A 2004 Chevy Blazer experienced issues with the bumper antenna throwing an error code, remote lock/unlock failure, and ignition problems. These symptoms suggested a potential problem with the vehicle's radio receiver module, possibly linked to a recent aftermarket radio installation. The installation likely caused a faulty connection in the antenna wiring. After a diagnostic test and repair, the connection was fixed, resolving the issues.

No accidents or anything, but I did get a new car radio installed a while back. You think they messed with the antenna wiring then?

The aftermarket radio installation could very well be related. A faulty connection in the cable or plug of the antenna could be the source of the error messages and malfunctions. A diagnostic test should be performed. If the car radio installation is the root cause, expect a moderate repair cost of around 95€. Visit a workshop for resolving the issue.

Thanks for the info! I took it to a mechanic, and it was the antenna wiring, just like you said. They fixed the connection, and everything's working fine now. It was, indeed, the aftermarket radio installation that had caused the issue.

The symptoms you describe, particularly the combination of antenna error, remote locking malfunction, and ignition issues on your 2004 Chevrolet Blazer, suggest a potential problem with the vehicle's radio receiver module, which is often integrated with the remote keyless entry system. Has there been any recent accident involving the bumper, or anything else that involves the antenna and its wire?
