Climate Control Fuse - keeps blowing
Climate control went out on Monday. Found a blown 10A fuse at the left kick panel and replaced it with a 15A. Turned key to ACC and saw Climate Control illuminate, so I figured I was good. Put covers back on, carpet back into place and checked cig lighter for a penny, just in case. Started car and light went out again. 15A fuse blown.
Is there a mechanical part that can be triggering the fuse to blow? Fan clutch, maybe? I've done Advanced Searches in the Forums and usual solution was fuse replacement. But, since I've done that already, I'm wondering if anyone else has seen other issues that may be driving the fuses to blow.
Thanks!!

I believe I’ve now got this narrowed down to a bad ac compressor clutch. Ive searched the forum and can’t find any parts numbers. Called local parts places, Napa, Autozone, Oreillys and no one sells just the clutch besides OE/Dealer. Has anyone else had luck buying one elsewhere besides OE and have a part number. Thanks

No luck finding a complete assembly at a wrecker? I've even seen them on eBay for not much.
A/C compressors are arcane things to me, and the SC started with an R12 model that required the separate oil charge and all. I believe 95 or perhaps 94 was the changeover to the R134a, and some early ones have been converted. Good luck!

Thank you. There are 2 sc400 carcasses at the local picknpulls, no sc3s. I figure, at 26yrs old, a salvaged one may give me problems down the line. I have a wholesale acct so I ordered one from the dealer. Wish me luck. I’ve had a rt regulator, both driver and pass door latch clips fail and now the ac clutch fail within a month. May just flip this car after this streak of misfortune.

Picked up the OE ac clutch from the dealer. My cost was around $225. I didn’t want to replace the whole compressor assy due to being still setup on R12. I’m going to try to replace it early next week. Wish me luck.

Ok, I installed a new OE ac clutch assembly 88410-24020. It wasn't too hard. I just had to remove the top radiator hose, battery and battery tray. I discovered that the clutch bearing failed, causing the clutch to wear and break the wavy snapring, 90099-07125, and then actually melt the coil assembly. I had to pick the second snapring out from under a layer of melted plastic. Installed the new parts, but couldn't figure out the gap settings. Started it up, air blew cold, but after a few miles on the highway, the gap must have been too far, as the clutch smoked the coil again. Thankfully, AutoZone sells the coil separately, p/n MT2300 for the Santech A/C Clutch Coil. Question is...does anyone have the gap setting for the clutch hub? I can find that the 2UZ-FE series motors are .35-.60mm, but I can't seem to locate anything on the 2JZ series. I'll swap to the replacement coil next week, but will get some feeler strips to gap this thing properly. I did buy 88335-14020 washer kit that came with 3 thin magnetic shim washers, but I can't rely on those setting the correct gap, can I?

Sweet! I was able to hit up a friend who is a mechanic and he accessed the AllData system, but he could only pull GM specs of around .35mm-.60mm. He advised me to stay around .50mm which is right in line with these specs. Thank you.
