Volvo Repair: Volvo s70 electrical, neutral safety switch, temperature guage

Question
I recently had the Evaporator replaced on my 98 S70. Since the repair I have had a sporaticelectrical problem. The sun roof, climate control. cigarette lighter, neutral safety switch temperature guage and (? abs? are not working ) They seem to come and go when i start the car. The lights will flash on these accesories and may or may not work. When they do not work the A/C is stuck in the on position w/o the blower working. I am affraid that the a/c unit will freeze and ruine the compressor.  Any ideas of where the wiring may be messed up?
Thanks
Ken

Answer
Ken, sounds like they didnt put the connectors back tightly under the dash when they removed it to do the evap.  It may also be a coincidence but the electrical portion of the ignition switch may be going bad.  Take it back to the place that did the Evap.  Roger
