I have a '99 Volvo C70 coupe (237 hp version) and I have a problem whenever I turn on the heater...?

Question:
...it seems that whenever I turn on the heater, this gross, pungent scent comes out of the vents...the only way to describe the smell is like an "old, urine-soaked gym sock." I only get this problem when the heater is turned on, not when it's on air conditioning. Also, when the heater is on, i get the smell regardless if a/c is on with it or not.

i have a 93 infiniti g20 and i need help...?


Could this mean I need to replace my cabin air filter or is it a more serious problem??

Answers:

Why are there noises under chassis during low gear or reverse gear?

i know whats causing this,i own a repair shop,and i have had to clean several heater boxes out this year,when one sets under a tree,or a mouse builds a nest in the heater box,the old leaves and stuff turns sour,and this gives of a bad odor,i just got done cleaning out a ford probe that really had a stink in it,it was so bad the owner would rather freeze than use the heater,so i got the pleasure of cleaning this out,i wore a mask it was so bad,but you might have to take the heater box out,and clean the whole thing,that's usually what has to be done to get it all,its pretty gross,when you start cleaning them out,you think its bad now,wait until you get in to the heater box,it doubles,what it smells like now,but to get it all out,that's probably what your going to wind up doing,is removing the box,and cleaning all of it,good luck with it,,i hope this help,s.
