Help find the problam !

[tomux25]

In some auto service , they where doing a tune up, for my 97 markVIII.
After this i founded that the headlight's/turn signals/dashbord light's are gone.
They claimed(auto service) that they have nothing to do with this problam.
I am sure they disconected the battery power, before starting to work on tune up.So first thing that i though the short circuit might happend, and i checked all the fuse's under the dashbord, and under the hood, all fuse's are ok.Is there anything else besides, those two fuse boxes, that i have to ckeck. Is there any relay's that can be related to this problam?How to finde out why headlight's , turnsignals, dashbord lights are NOT working.There suppose to be some thing that relate's these three things, because all those problams happend at the same time.Pleace need help on this.

dont assume that they disconnected the batt. half of the time i take my car in the radio channels are still there when i get it back. as for the problem, if it could have somthing to do with that, them perhaps.

the problem

they would not disconect the battery for a tune up. it is unnessary, and not incorpirated in the laber time. my ? is do the wipers still work? if not i have an idea. outher wise do not go yell at the shop. trace the problem, get under ther and check every thing. use a test light and a good ground sorce. use it to check all contions, splices, fuses, relays and any thing eals that is around there. let me know about the wipers.

I had a similer problem and it was a small cerkit that controles all that and was able to get it taken care of in about a day. I would check AllData for a service buliten :bash:
