1998 Chevy Camaro Winshield wipers

Interior problem
1998 Chevy Camaro 6 cyl Automatic 117, 00 miles

Hi! I have a question.

I just had my dealership replace the ignition in my Camaro because it wasn't starting up. This is the second time I've had to had that procedure done, and as I understand it, in order to do this you have to remove the steering wheel column. Well, the first time this was done a locksmith came out and did it for me. When I picked up my car, the horn and bright lights no longer worked at all. This week when I picked up the car from the dealership, the winshield wipers had completely stopped working! When the car broke down last week, it was raining, and I was using the wipers- they were working just fine then. When I called the dealership about this problem, they said that the wipers not working could not have been caused by the ignition replacement that they did for me. I just paid over $400 to get this done and I can't afford any more work, in the meantime I need to be able to drive in the rain for work. Is the wiper malfunction possibly something that could have happened when they replaced my ignition? I just need to know if that's possible in order to try and get them to fix it. Or if there's any DIY information or suggestions you may have to offer. It would be so much appreciated.

Thanks in advance!
Lauren
