OT: A different car repair question...


Recommended Posts

I've been driving a 94' Cadillac Seville SLS and yesterday I noticed the A/C wasn't doing much (it was 97 degrees out) and when I got home and parked the car I noticed a thin plume of smoke coming out through the right slit of the hood.

 

When I walked around the front of the car there was a pungent smell lingering in the air. Something like burning rubber maybe.

 

I talked with my brother today and through a battery of amateurish tests I believe it has something to do with the A/C system. It doesn't do the smoke/smell bad thing when the A/C is off. Only when it's on for a few minutes.

 

Anyone care to weigh in on what it might be? Bad compressor? Bad belt? Low/no Freon? ???

 

The car has only 45,000 miles on it believe it or not and that's after the 1,600 mile trek from Maryland to Austin, Tx.

Yep, if it's smelling like burning rubber it's likely a belt that's been slipping. If that's so, it's probably due to a compressor starting to fail, or the clutch coil or bearing going south.

That's from the information that the thing isn't cooling as well as it did before.

 

This information is not warranted to be the cure for your POS's ailments.

I remember when my A/C went out... one of the nastiest smells I've ever experienced. Not the rubber belt burning, but the actual compressor went. (Whoo! :freak: )

 

Have it checked out by a technician and don't run the A/C again until it's been checked.

It's gonna end up at the shop but it's interesting to see how these things work.

A '94 Seville has the Northstar engine. Those suckers take up a lot of space, don't they? I was on the original Northstar project team in Livonia, MI, and I doubt you'll see much from underneath. But if you do, look to see if the compressor's spinning at a comparable rate. As the car IS 10 years old, the compressor crapping out is a safe bet.

I started out with NOTHING...and I still have most of it left!

Reminds me of when my last car's AC clutch went bad. THe motor just seized up all at once and refused to turn.

 

The belts are still spinning, though. The friction created when belts rub across a pulley account for that nasty smell. What you want to look for (and check all of your belts) is any sign of which look "polished" or worn on the bottom.

...think funky thoughts... :freak:

Yeah the Northstar V8 is badass. I'm not gonna run the AC until I have a mechanic to look it over. Sounds like the compressor is toast from what you guys are saying. I'm glad summer is almost over cause I can't handle shelling out $1000 right now.

A roach clip?

 

One thing to remember is that the compressor is probably running when you have the defroster on, even if you have the temp control on hot. This is true of most modern cars, so bear in mind that you'll either need to fix the problem or bypass the compressor somehow if you need the defroster. That won't be for a few months since you live in Austin, you lucky dog.

Good point Henry. The clutch coil can be easily unplugged though and then if the clutch bearing is still good it'll stop the belt problem until Jode can get it fixed.
