First of all, about a month ago my #10 & 11 fuses for my blower for heat/ A/C blew. I took it to the dealer and they fixed it by replacing the 2 15A fuses and couldn't determine the cause. Well, it happened again and this time I didn't want to drive all the way to the dealer and drive a rental for a day, so i decided to replace the 2 fuses. Well, i replaced them both and they blew again. Does anybody have any idea why this is happening?

Fortunately it was mild today, but i won't be this lucky for long, so i guess its another trip to the dealer at 2600 miles. Thanks if you can help me.

 

I'd say Use a bigger fuse, but you already did that. You can't keep going too much bigger or the wires will melt instead of the fuse blowing...

Did you install any after market electronics? If so, as you sure you tapped into the proper wires?

 

Yea, I think you should look at the Kenwood music Keg you added, or maybe the FM modulator (if you installed that yet)

 

either theres a short(Id expect it to blow IMMEDIETLY so unlikely) or perhaps an electronic cross somewhere.

or most likely, you tapped into the AC power in the console area and thus are blowing the fuse.

 

The car is completely stock except for window tint and thats obviously not causing electrical problems. I have NOT touched ANYTHING electrical/stereo at all. The stereo stuff is getting professionally installed next week.

The fuses are 15A stock and i replaced them with 15A, i am not going to up the amps and cause more problems, it should work properly with 15A's in there.

The fuses may have blown immediately because all i did was put the #10 & 11 fuses in there and turn the key and turn the A/C **** with no results. Then i turned the car off and checked the fuses only to find that they were blown. I don't think it makes any difference, but the fuses originally blew right after i accidentally slipped off the clutch and stalled the car. Anyway, any more help imput as to what the hell is wrong with this thing would be greatly appreciated.

I bought a new car because i wanted something reliable, not something in the shop 2 times before the 1st oil change, WTF.

 

I would say to double check all the fuses to make sure there is not a misplaced bigger fuse which would conceivably blow your fuse continuously. Anyhow can you determine if it blows after say turning on the AC, or turning on the lights, opening the doors, etc..?? Seems like your fuse is getting to much power, in which case, it may be a misplaced oversized master fuse...

 

Sorry for my assumption on stereo installation.

Are your 3-digi meters working?
Have you ever removed your center console?

I beleive those fuses are also related to your meters.

Maybe you removed your center console to check out fitment of something, and forgot to connect (or misconnected) the wires for the meters or for the blower box?

 

Nver removed anything, everything else in the car works that i know of. If a fuse ws misplaced then it was by Nissan from the factory or it was the dealer so that isn't likely. The weird thing is is that it worked fine for a month or so, then my foot slipped, it stalled and the blower stopped working. I think i'll just take it in and make them fix it even though its a PITA
