No radio, clock, power ports

I have a 02 2.7L ext cab. It is 100% original, stock everything.

I boosted my girlfriends volvo the other day. I did not ground the booster cables. I did not hear or see anything unusual. the volvo started, everything was fine. Until I realized the next morning that my clock, radio and power ports including ligher port do not work. I checked the fuse, it was blown, replaced it. Still a no go. I have not checked every fuse in the box, but I did use the manual and suspect I replaced the right one, it was blown. So of course now i don't know what to do. Any suggestions?

Thanks

 

welcome to TW, if you didnt check all of them I would say go back and check the rest of them! and maybe check the ones under the hood as well

 

welcome to TW.. i would double check the fuses.

 

Thanks for the welcome.

I check the rest of the fuses, there was a ACC fuse under the dash that was blown, I replaced it. Still no luck. There appears to be an AC power Relay in the fuse box under the hood. Any chance it is that? Any way to diagnose the relay?

Thx

 

I am nor surebro. Hope someone else has more info

 

If there is another fuse with the same part no. on it near by (preferably for something minor, like the horn) you can swap it out and check your radio to see if it works.

If you can get a wiring diagram for the systems that would be helpful. It might also tell you if there is a fusible link in the system somewhere. Those can be hard to track down when they burn out.
