I remove the under hood 40 amp acc fuse, now have no power to climate display, defroster, heated seat driver side power mirror.

 

put the fuse back in?

 

The fuse was replace still no power.

 

did you check the new fuse for continuity?

 

Yes there's continuity, could it be a relay?

 

could be. you are going to need to pull a schematic and then trace the wires with a dmm to find out where the power stops.

 

Do you know where I can get a schematic on line

 

the only possible solution for that I would have would be google. and that is probably gonna be a good bit of searching. you may be looking at buying a hayne's manual.

 

some more info on why you are doing what you are doing will help us help you.

to test fuses i let the car idle while using a DMM set to VDC. i ground the black lead then touch both metal tabs on fuses while they are in-place. measuring 12-14VDC on both sides of a fuse tells you it is good. voltage on one side only tells you it is bad. no voltage is a sign that circuit is not powered (either through a relay or other component). test the underood fuse box as well as all cabin fuse box(es).

from this test you can identify what fuses are without power and that will correlate with a schematic.

for a schematic you can buy a Haynes manual for your car for under $20. if you want to DIY, buy the manual. otherwise pay a mechanic >$60/hr to troubleshoot for you.

 

Air conditioner was not blowing cold air, check under hood air conditioner clutch fuse it was good, relay was good and 40 amp acc fuse was good after removing and replacing 40 amp fuse power was lost to climate display, heated seat, blower. Radio is receiving power it works fine.
