Replaced the battery yesterday and stupidly put it on backwards. I blew something because after I put the battery right, my gauges and my AC unit don’t work. Radio works as do my seats motors and most other things. I checked all the fuses and they seem to be visually OK,

Can fuses be blown without being physically broken? Also, how to check for faulty relays? I’m hopeful that it’s one of these simple fixes.

 

need to know what kinda car this is and year first

 

Yeah I told you I was an idiot.

2001 Chrysler T&C. Got it working, however. Turns out it was the Hazard Fuse (go figure) for the instrument panel and a couple of other fuses for the AC control unit. Everything's a go now!!
