2004 GMC Envoy SLT possible electrical problems

I recently tried to start my SLT and thought the battery was dead. Lights, radio ect all work fine however the clock on the radio always goes back to 12:00. Car will strat now "most of the time". There is a clicking noise so it might be altenator or starter not sure. When I remove the key it will continue to make a clicking/grinding noise then turn off.

    My car has been having th engine light come on and it seems that our local gmc dealer cannot figure out what it is. Well a year later here i am and they finally figured out it was a starter after having my car die completley. but other than that i absolutley love my envoy, a classy car thats hot

    I have a 2002 GMC Envoy, something is draining the battery, the shop has installed a new alternator, new battery and the battery still drains in 24-48 hours. The shop has pulled all fuses and see the drain but can figure out where the drian is coming from, any suggestions?

    u may have a damaged starter drive and damaged flywheel gear teeth, pull the starter and check the drive gear for wear, while it is out check the flywheel for damaged teeth.

It sounds like you need a regulator for your alternater it is reversing polarity there for draining your battery and reseting the clock. it is located on the back of your alternator.hope this could help.

It sounds like you have a grounding issue somewhere. Look up a fuse diagram for the cabin fuse panel. Start from there.

Would a dead battery stop your key from turning on in a 2003 gmc envoy


Sounds like a flat battery. Just enough to power your lights but not enough to power the starter motor. Try recharging the battery.and check battery connections are good.

I just installed a radio on my 02 envoy slt and now the backlighting on my insturment cluster and a/c don't light. All other dimmable lights work ie window button lights information screen and a/c...


Might be using the current for the cluster lights to power the radio, or a problem with the ground connection.
Check the wires you connected the radio to.
Try unplugging the radio to see if the lights work again.

Car no start problem is sometimes very difficult to confirm. You try all the possible things, but still you get no fault and problem is still the same.--------
In that case, you need to check few things individually.
Check the spark,the battery,the crank, the fuel and other most possible parts. Click this link below for more details:-- http://howtobyme.blogspot.com/2011/10/car-troubleshooting-tips.html

My 2004 envoy starts but there is no electrical. the windows radio tail lights reverse lights dashboard lights ac heat dondoesnt work. but the odometer still works so there is electric and all the fuses...


Sounds like a bad ignition switch. There are 3 main ignition circuits coming from the switch, and one will control the engine and starting. One circuit is probably dead thru the switch, causing all the accessories to not function. I would tr that first.
