We've been doing some work on our RV over the past few months. We had hardwood floors installed, replaced ceiling lights & put a new stereo in the cabin. We've now got a problem with a few things not working, including a few of the re-installed lights, the cabin A/C, water heater, & fuel pump to the generator. We've checked all the fuses & know we need a new battery, but have had it plugged into the house. All the items not working are on the left side of the vehicle except for the cabin A/C & all the plugs on the left side are still working. I know we need a new battery that is completely dead now, but not sure if this is the problem since it is plugged in. We plan on replacing the battery this weekend an hoping that works. Any other ideas?

Check to see if one of the circuit breakers on your inverter has tripped, or if one of the GFI outlets has tripped.

Check to be sure you power cord is completely plugged in on the coach side. Mine has a twistlock plug on the MH side and had come loose enough that I only had one side of the power.

X2 on the GFI outlets. I had this happen when I had my coach. The GFI actually was bad but when I replaced it everything worked just fine. They do go bad. LOL.....

Its a 12V supply problem somewhere as the Lites,water heater,AC thermostat and gen set fuel pump all need 12V to activate things

We did some more work this weekend & got the fuel pump/generator working. It turns out the fuel pump was bad & just replaced it. We didn't replace the battery, but we did charge it up. Now we've got it narrowed down to what I think are two separate problems:

1) Cabin AC & Front fans - The AC fan and the in-dash switch both have electricity going to them, but still won't turn on. Guessing just a bad switch? We did put a new stereo in, but since everything seems to be getting power I don't think it is a factor. Also we have some front fans that won't turn on either.

2) Water heater & left side cabin lights - Still not sure. Is it possible some wires got switched when putting the lights back up & would this affect the water heater or cabin A/C? Or is it possible the previous problem could have something to do with this?

It seems like everytime something gets fixed something else goes wrong. Might just have to take it to someone. I've got the Good Sam's Club Platinum with Technical support. Has anyone had any luck with calling them?

Your water heater and your lights may be lacking the 12 volts. Check all of your fuse panels for a blown 12 volt fuse.

It turns out all the electrical stuff was a partially blown fuse that we somehow missed everytime we checked them, but still haven't figured the cabin A/C out. The blower is turning on, but the compressor isn't unless direct power is connected to it. Also, the freon is full. Any ideas?

It would really help if we knew what brand and model of motorhome your having this problem with!

Sorry, it's a 1993 Seabreeze. We just drove from Dallas to New Braunfels only running the overhead air on a 105 degree day and it was hot!
