No dash lights

Demon73 · Oct 11, 2012

I just installed an after market headunit in athe 2000 Mazda Mpv with a wire harness adapter. No brainer it plugged right onto stock harness it is labled so that you know what wires go where. Stereo works great but I now have no dash lights. The turn signals, low fule lights work but no lights on my speedo or tach. I have checked all wiring and fuses under the hood and under the dash. Any suggestions will help thanks!

Check the orange and orange white wire in the harness. If they are connected try and disconnect them.

Sounds good ill give that a shot. I do have the orange wire hooked up. Thanks!

I disconnected the orange wire. And still no dash lights. Orange and white is not connected. So I pulled out the new radio and slid thw old one in. Hooked everything up and still no lights. So put new one back in ans checked all fuses I could find. Under dash driver side and under hood driver side. Also pulled out interment panel and checked lights they are all good but found that there is no power where the light goes. Please anyone got any more ideas. Thanks!

Something could have shorted, id take it to an auto shop to see what they could think.

check the light bulbs

prolly didnt disconnect your negative off of your bat and shorted

AxT4430 · Oct 21, 2012

Theres prolly a door panel or panel underneath your dash, somewhere, anywhere where you havent checked and a fuse shorted..

Could maybe have shorted and ended up blowing a fuse able link?

check your illumination fuse. thats why i dont connect illumination wires anymore. even though they are color coded, i went through hell when i connected a single din on a honda accord. and btw, your tail lights might not be working as well

Demon73 · Oct 21, 2012

Thanks for the info. It's a 2000 Mazda mpv and tail lights do still work. The only thing thay I've found so far are the illumination lights for the dash. Any one know where i might find the fuseable link that might have been fried by not disconnecting the batt. At insulation time.

I was checking the ground wire conection and ended up pulling out the interment panel. I was pulling out lights and checking for voltage. I found that there was voltage 10.75 volts on both sides of the connecting point where you install the buld. There was no voltage with the light switch off. So what happened to the ground side of the connecting point. Any ideas? I was looking online an pull up some diagrams it looks like I might have done something to the TNS relay? Anyone know anything about this?

Found quick fix. But now the check engine light is on. I grounded one of the lights in the instrument cluster and have lights now! But it caused the check engine light to come on and stays on even after disconecting the ground jumper. Any ideas?
