Strange sound

[enawazh]

hey guys
lemme start by sayin that club202 is the best i luv this place i have learnt so much about the car. however ive had a lot of problems with it too nostly vaccum eaks and stuff like that.

i have a 95 c280 145 000 miles.
i was wondering about something.

while driving, with steareo and ac all turned off, i can hear a sound in the dashboard. it sounds like running water. just wantd to know if anyone whould know what that could be .

[fastmayte]

maybe the heater (coolant) valve is not turning off competly? does it blow hot air when u run it in EC?

[enawazh]

i currently have no cold air blowing from the ac
if temp is on high then it blows hot air but even if its on low, its not as hot but its warm.
basiclly no cooling
i hope i answered your question correctly.
