Dealer said some BS...

[Astroman]

I took my car in this morning to get it checked out. My A/C won't turn off after I turn it on, I had a problem with my driver side headlight, and I also noticed the egg smell from the exhaust. I just got the call back and they said it's "normal" for the A/C to stay on, since apparently the Yaris has a aftermarket air conditioning system. They said my headlight bulb is bad, which is BS because it's good. I just have to press on some VERY hot wires on the connector that is actually coming apart and it comes on. They said there was nothing I could do about my exhaust because there is no such TSB on the yaris hatch (BS, I have it!) and that I voided my warranty because I put on a non-toyota aftermarket exhaust. I have the TRD muffler, is this true?? I'm calling bullsh*t on them. I'm going back down there at 11am armed with proof I have a TRD muffler and the TSB. I'm also going to point out that the connector is actually melting. My aftermarket headlights are rated at 55/60, so there should not be any problems.
