Question about 1992 Cadillac DeVille
I have a problem with the #5 fuse blowing in the under dash relay box located on the right side of the dash.It protect the a/c,egr solinoid,p.s. pressure switch,the tcc solinoid,and the cannister purge solinoid.plus the shift solinoids in the trans. but the fuse only blows when turning on the a/c.The a/c blows cold for one or two minutes then blows the fuse.The fuse is a 15 amp and is # 5 on the relay /fuse panel.I have tested all the solinoids and pressure switchs plus replaced the bcm/ecm but all i have to show for all my work is a pile of blown fuses. Any ideas Everything works fine until i turn on the a/c then the transmission has to be shifted manualy
I can't locate the under dash fuse block on my 92 cad sts. Help please. The AC/Heat blower will not come on, I think I have a blown fuse.

The conector for the a/c compressor comes with a diode that keeps power from returning after the compressor cycles off. Check or replace the connector/and or diode and see if that fixes the problem

Thank you but as it turned out the a/c clutch magnetic coil was shorted internaly. There was a small water leak dripping on the clutch apparantly for quite some time that caused the coil to short and blow the fuse. I replaced the complete clutch and coil now everything is working fine i also repaired the water leak so hopefuly that ends that problem .It is hard to believe so many systems are protected by a 15 amp fuse.The A/C fuse blows and then the transmission doesn't shift what was G.M. thinking? Anyway thanks again JDABE
