Q: How to remove and replace Horn of Chevrolet Cobalt,HHR and Saturn ION?
A: On Cobalt/G5 and ION models, remove the left Headlight housing. On HHR models, remove or peel back the inner fender liner. Disconnect the electrical connector from the horn. Remove the horn mounting bolt and remove the horn. If the horn was removed with the bracket attached, transfer the bracket onto the new horn. Installation is the reverse of removal.
