Sierra Problems

[JGamble]

Gents,



My lady friend left for Vegas a couple days ago, leaving me her new (to her) 96 1500 Sierra with a 305 TBI. Well, she is asking me fix some gremlins in the elec system.



First off, the truck has cab lights that dont work. When I pulled them off, they didnt even have the wires attached. Solderless connecters were there, but the wires were not connected. I connected them, nothing. Ideas? I cant trace the wires all the way to the engine bay... . I am lost.



Second, the power door locks. I get one, yes ONE chance to use them. They will lock or unlock only once. Then I must let the truck sit for a hour or more (running or not) and all the sudden, I get another chance. WTF??? I havent ever seen this before... ... .



Third and finally, the interior cab lights. I have the personal spot lights working for the sides on front and back, but the main cab lights do not work. Could this be a issue with the plunger switch on either side of the dash and in the rear door frames?



A little FYI, the fuses are fine, all of them. It seems as though this truck was a hoodlums toy who thought he/she could add extras and didnt know what they were doing. I would really like to have this beast fixed before she comes home, so anybody got some ideas? Thanks in advance... .



Kind Regards,

John

Door locks I believe work off a relay. There is 2 locations for the fuses, under the hood and on the left end of the dash that you pry the cover off when the door is open. Check the head light switch, the interior lights are controlled by it as well as the doors.

So another update, I looked at the relays, they are all screwed up. Second, the interior lights, threw in a new bulb for front and back, and the dang thing stays on even with the doors shut and then engine running. The backlighting switch wont cut it off as should and the Dome Cutoff doesnt work either..... and today, I get to tell the lady friend the news... ... . this should be fun... .
