check your battery terminals, cables and make sure there is good contacts and no corrosion at any place on the battery cables

This is not hard but tricky because the trim plate around the radio has clips that hold the trim plate very tight.Use a plastic type flat tool or flat screw driver wraped with tape or a shop rag to avoid damage to the plastic trim and pry the trim panel around the radio loose. remove all elec connectors.Then remove the screws that hold the radio in place and remove all elec connectors.

I'm not sure if this would help but I know that the Colorados are in the same family as the GMC Canyons and Isuzu's i-series trucks

Try resetting the radio, turn the radio off and disconnect the battery for 30 seconds. Make sure the RADIO IS OFF OR YOUR GOING TO BE ASKED TO ENTER THE RADIO CODE TO HAVE THE RADIO ACTIVE AGAIN. After the battery has be reconnected, turn on the radio and reset your clock and stations. Your CD plays should be working again too. Good luck and hope this helps.

Both my rear brake lights went out at the same time. o7 chevy colorado. What are my options?

This happened to me. Problem is that the wiring and transercase ECM under the floor mats are not weather sealed. To fix the 4X4 ECM youll need to take up all the flooring and sound proffing. They hold a lot of water and never real dry out. Next to replace the ECM its easyest to take out the drivers seat. Four blots hold it to the floor. The black box under the seat (under the floor mates) is the ECM for the transfer case. Replace that and get the conections in the wireing dry and you should be good.

there is a fusable link between the alternator and the starter it is the wire connected to the 10mm bolt on the back of the alternator and goes to the strter please rte if this was helpful

On the right lower of the radio there are 2 arrow buttons. one changes the hour and the other changes the minute.
