Electrical Gremlins? ABS A/C etc

[emmvette]

I think about everything is sorted out now - except the A/C. Keeps blowing fuses and can't find where the problem is.

Check the resistance of the AC compressor coil first - should be about 3.4 ohms.
When that fuse blows, you get SYS messages and not much else works either.

I will say that I've found a few things "autocross related" worth mentioning:

- door switches will indicate "door open" in spirited cornering
- doesn't take much stress for battery connection to be "iffy" and give intermittent "sys"
- hub play can lead to ABS light

I always thought "I never kick into ABS", learned different when one day the only spare hub I had was from the '88. Boy did I ever make some flat spots that day.

Sounds like you're on the right track though.

Cheers,

I haven't done this yet; guess its time to pull the plenum. Will the coil cause the fuse to blow?

By the way, here's a pic from the other weekend. It was kind of funny, somebody took this pic right as I realized my ABS was gone - it looks like I slid a little right as this was taken - I'm a long ways from the near side cone!

ABS or not, I had a great time and the car performed very well. Now the driver - lots to learn and having fun doing it!

More to the story - I fought an intermittent AC fuse blow condition on Mary's 91 L98 - drove me nuts for several years - turned out to be a bad clutch bearing and the clutch finally ate into the clutch coil causing a dead short to ground.
Replacing the bearing and coil fixed the problem. Did not have to replace the compressor assembly at a much higher cost - phew ...
