Q: How do you remove the antenna mast on Chevrolet Colorado and GMC Canyon?
A: To remove the antenna mast, use a small open-end wrench to unscrew it. Take care to avoid scratching the body by surrounding the base with masking tape. If the antenna base/cable assembly needs to be replaced, remove the glove compartment, right door sill plate, right kick panel, and detach the lower rear portion of the inner fender liner. Disconnect the antenna mast cable from the radio cable and attach a fish wire to the end of the cable. Pass the cable and grommet through the hole in the cowl into the fender opening. Then remove the cowl cover and the antenna mast base mounting bolts.
