Title: Blowin' A/C Fuse
Post by: Matthew311oh on June 15, 2011, 02:48:58 PM

I've got a 99 Suzuki Grand Vitara 2.5L V6.  I went to charge the A/C and realized the compressor wasn't spinning up.  I checked the fuse and it was blown.  I  replaced the fuse and the clutch immediately engaged and spun for a few minutes,  I went to check the pressure on the Low side and it was low,  I started filling it to pressure and the fuse blew again.  Replaced the fuse several times.  Got the system to the correct pressure. Now I just need to find out what's wrong with the electrical system.   Any body have any ideas?

If I'm not mistaken, that fuse feeds only two circuits - the a/c condenser fan and the a/c compressor clutch coil - gotta be one of those two.

When that happened in my 2001, it was the fan that was blowing my fuse. I'd check that first. I hear it's a fairly common thing with these.

It may be the fan, I hit a deer, and the fan seemed ok, but was seized, it kept popping the fuse.

Not quite, it's only the Condenser Fan.

The clutch coil power comes from the Rear Defogger fuse!

When the fuse blows the Compressor clutch disengages though?

Ummm - not according to my FSM - fuse #29, A/C fuse feeds both the a/c fan & a/c compressor clutch coil via their respective relays - of course we could be looking at different vehicles or different diagrams.

But then again - having looked at four different sets of drawings - all are like that - just the fuse number changes.

Oops, you're right.

I misread a 3  - thought it was a 9.

Should the condenser fan spin freely with the engine/power off?  Mine does not.  I think this might be my culprit.  Thanks guys!

Just to update in case anyone else has this issue. ..

My condenser fan was locked up.  That was blowing the 25Amp A/C fuse.  I unplugged my fan, replaced the fuse and the A/C worked fine.  Replacing the fan this week.

Thanks for the help guys!  You're the best!
