Wink 323ci Instrument Panel/Conv Top/Air Conditioning

What Mechanic Did: Touched hot wire to ground wire near the driver seat fuel pump

Impact: all gauges on instrument panel stop working, but light still on... air conditioning stop for a while and convert top stop, no bells for door opening with key in ignition and no seat belt bells any more....

What could have happened? Tripped circuit/ tripped power supply what? Help.

Driver seat fuel pump? What!?

Quickly touched the wires or connected them then realized?

Have you checked the fuses? Check the affected area for burnt wires?

This isn't your job to research, the shop is liable for repairing the problem they created at not charge to you.

Thanks

Checked the fuses already and all seems to be functioning .... I will check them again..... The mechanic was my brother helping with diagnostics and don't want penalize himfor trying to help me if I can avoid it... Any suggestions on what could cause all these to fail at just one touch.... Are that any parts that are common to all the pars affected like a power supply or such?

Maybe there is a cutoff switch to the power convertible roof, but how would the air conditioning be affected? Is there a main relay and could have such an effect?
