Re: A/C Fuse Keeps Blowing

you can check the amp pull at the a/c relay--to know for sure. The coil could be shorting internally- causing the fuse to blow- and yes i can be intermittent-- you can also check the resistance of the coil at the a/c relay- should be around 3.5 ohms usually depending on number of windings etc. if much less, then definitely a shorted coil.
