tech = JK
question = I removed the factory stereo, replaced it right away, and
now the red blinking light on the stereo doesnt blink. The fuel guage
doesnt work, neither does the temp guage, auto headlights, and I think the
ac quit cooling.The stereo quits when engine is running but comes on
when engine turns off. Whats the deal?






JK:
Thank you for the tip/donation.
OK. I will need some more info, and need you to check a couple things first.
First, why did you switch the factory radio right away. Did the aftermarket radio work at all,
or did you even turn the key on to try it. If you did turn key on, did you notice if any of the
problems you described where there with the aftermarket radio in and turned on? I assume
the aftermarket adapter is no longer attached.
There are a lot of wires behind the radio that go to ignition switch, and the gauges cluster.
Be sure to check all of the fuses. Rt. side of dash fuse block, lf. side fuse block, underhood
fuse block. Check all fuses with a test light with the key on and make sure none are blown.
If the factory radio is bolted back in the dash, pull it out, keep all wiring attached.
Disconnect battery for a minute or so, then re-connect battery and start car and see if any
symptoms change.
This may sound like alot to do, but there are some very odd things happening, and i need
to get this info to help.
I will wait for your reply, then i can get more in depth with schematics to find out what
happened.
Once again, thank you for your tip/donation. I will do my best to get this straightened out.

VISITOR:
THANK YOU!  I will go over these things tomarrow. I work nights and my time is cramped,
but I will manage. When I put in aftermarket stereo and turned on the key, It just lit up and I
couldnt get it to work right. After paying money for the adapter and the stereo, I was
frustrated, so I changed it back.When I first hooked it up I didnt disconnect the battery, and
it blew the fuse for the stereo.Everything is back like it should be exept for a missing fuse in
the cruise controll slot. I used it to replace the stereo fuse. 10 amp. I will check the other
fuses tomarrow.The small red light that usually blinks on the stereo is no longer blinking.
