As the subject states, first I thought the problems were related. Does not seem so anymore.
Problem #1: the car vibrates really bad in D and R, turning on the A/C makes it unbearable. I looked at the accessory belt and it was noticeably flapping while in D. The RPM were going down noticably when switching between N and D. I did a search on this site (BTW, lots of great stuff, really helpful) and it looks like you guys would vote for the tensioner. I took it out today. Nothing obvious, perhaps the spring is weak. What are you guys recommending then? A new dealer part or a junkyard self-service? BTW, 4 months ago I did some work in the very same area: replaced a noisy idler pulley and the belt. Everything was fine for ~~ a month or so and then the noise in D started.
Problem #2: the air does not blow into the cabin, only on the windshield no matter what is selected (A/C or vent). A hiss can be heard from under the dash. Initially I thought my problem #1 was just a pirate air getting through a broken vacuum line. Nope. I blocked the vacuum grey line on the throttle - the idle speed does not seem to be affected at all. Does anybody have an experience with this?
