every time i turn the Auto climate on i get this gurgling like someone slurping through a straw behind my dash.
when im driving it seems to go away so i guess its like somehting is low on pressure. could low coolant or a/c fluid do this? thanks for any info
also i looked through the FAQs and mod Faqs and i remember reading about this somewhere, but cant find it again. maybe not in the faqs but in an old post

 

the coolant can make noises when it flows through the heater core. i noticed this on a 3rd gen. the a/c is used when the defroster is selected so its possible for it to make some kind of noise, but there is mosly gasses in the lines with just a bit of oil to lubricate things.

take off your radiator cap and start the car. watch to see if the coolant drops inside the rad. top off if nessecary
