A/C blowing fuse.. Any idea?

[ck_chino]

hey if ur spare is 1.4 ohms thats also much too low

do the math i= v/r...12volts/1.4ohms = roughly 8.55 amps

however initial engagement of the clutch will draw more of this prob hit 10 amps and more which is why it may not blow instantly but yea u need new coil

have you heard of the theroy it takes more power to get something started? but once started its less power to maintain it?

in addition cars are are more than 12 volts......13 to 14 volts running which is even more amperage.


and to answer your question .........yes i have done the replacement of the coil alone in the car. its not that bad once i look back on it, i had to remove the rad and make sure you have a set of quality snap ring pliers.
good luck

Appreciate all the incite!
My spare is 4.1 ohms at the unit.
I did my check today at the wiring loom upwards near the wiper fluid reservoir (on the bad one). My main issue is that; if im checking resistance on a solid line from the compressor unit to ____? (relay? still looking for a diagram) .. Then is this the "ACTUAL" resistance of the unit, or of the entire line itself. I'm not sure if that really makes a difference but in my eyes it would make more sense to take direct resistance from the unit itself, however its relatively impossible with it in place..

Anyways! It looks as if ill need to swap units..
I may just take it somewhere with my other compressor in hand and get them to pull the gas, swap the unit, and dump the existing r134a back in since the swap was done less than 4 months ago and the system should still be fairly up to par..

I'll keep tinkering..

And yes, getting things in motion requires the most energy; like going back to the gym in the winter months :P Or getting my damned A/C fixed! lol

Appreciate the help
