Engine vibration.....when heat/AC is on

[coolcat]

Hi all, I'm new to the post:) . Just got a new "04 Accord, almost 2 weeks old. It's a 4 banger. My first Honda. The engine vibrates, when the heat/AC is on, also the engine fans come on......... The dealer says is 100% normal. Is it normal?:rolleyes: Anyone like to comment? Thanks!!!!!!!!

The A/C does change the RPM a bit when the compressor kicks on. Many don't even notice. The compressor is also used for defogging.

Welcome to the forum!:)

Thanks for the quick reply. However, why would the engine fans come on???:blush: :blush: :blush: Thanks!!!!

The fans are supposed to come on when the compressor is on or when the engine temp is at normal running....180, I think. Inspector1 would know or I can look it up or I can ask the prince.....if you need to know.

Sounds like your car is normal to me.....:D

Thank you! We really like her! I really dread trade in time, we've added so many accessories & starting over will be a pain....& I know he'll want all the same things! At least there's no hurry, no trading until they come out with another one more tempting.....like more HP.....that would be hard to resist!:D
