[s-cars] HIR bulbs & AC question

[Kevin Day]

Hi all,

I installed my HIR 9012/9011 bulbs from the GP last night.  It's a
dramatic improvement over the stock setup.  Even my wife noticed.  
Thanks to Dave F. for setting the deal up.  

Re AC: When I turn the "snowflake" on at idle, the engine gets quite a
bit rougher and the whole car is subject to vibration from the AC.  
Is this normal?  Somehow I doubt it -- it feels out of place on this car.  
Any danger to running it like this for the time being?  I am a little
worried about the compressor seizing up and breaking stuff.  It blows
cold air and seems fine aside from the vibration.
