Hello!

New car! 91 9000 Turbo! I've wanted one of these since I bought my first piece of crap automobile. I saw it sitting at the end of someones driveway- and scoffed it up for a measly $1100. Dealer serviced- tons'o'records (New turbo unit too! :D ) It only needed an a/c compressor clutch. The dealer told the previous owner that the entire compressor would need replacing- "a $2000 dollar job" they quoted. So, she sold.

I replaced the compressor clutch. Good as new! Boy, does this thing go. Welcome to the state of independence- indeed!

Just a quick question about a noise I'm hearing in the cabin on idle-
The car idles fine: just under 1000 rpm- smooth and quiet. However, there is a slight vibration sound from the passengers side. Inside the car it seems to be coming from the engine compartment, but a look under the "bonnet" (sweeeeet) shows nothing but a silent 2.3 liter turbo idling happily. The vibration is of low frequency, and is moderately loud. Thought the belt might be loose, or a pulley warped. None appear to be. The repair bills say engine mounts all around only 20 or 30k miles ago. What is it?! :roll:

Confused in Maine

I hope you are not refering to the cabin air temperature sensor just below the heated seat switches. Lint caught in the motor shaft frequently caused it to make a noise.

If the noise is from the sensor, you have very little to worry about. Just pull it out to clean it. Don't know what would happen if the sensor is dead. Don't know how the ACC reacts when it can not sense the cabin temperature.

The cabin air temperature sensor will go on for about a minute or two even after you shut the engine off.

Four minutes actually on the later ACCII cars.


I just changed mine today on my 97 Aero, five minutes and CAN$130.00.

I tried cleaning mine with compressed air used for cleaning computer components. Not a good idea! I over revved the little fan and it started ticking more loudly! I recommend you take the component out to clean the fan blades to avoid this problem.

If this component stops working then the ACC will vary temperature randomly, usually too hot.

I'm almost certain its not that sensor... It makes the noise regardless of the on/off state of the ACC system. It's a vibration you can almost feel through the seats, which is why I thought it might be coming from the engine compartment at first. It's actually quite loud, with a 3 or 4 cycle per second frequency. The car isn't misbehaving at all- The noise is more of an annoyance/embarrasment. <img>
