Blower stopped working after trailer hookup
We bought a camper last month, soon as we plugged it in, the blower stopped working. We have checked fuses to no avail. Any suggestions? I am no mechanic 🤷🏻♀️

Unfortunately, no, it won’t work at all now. I have an electronic climate control system, if that makes any difference. Also, my heated and cooled seats still work 🤷🏻♀️

Check fuse f51, it provides power to the blower thru a relay. This fuse should have power at all times. Check both sides of the fuse for power.
Check f45, it provides power to the blower relay that's part of the battery junction box. It should have power when the key is in the run or accessory position. Check both sides of the fuse.
And check F15, it provides power to HVAC module that controls the blower.. This fuse should have power at all times. Again check both sides. Pin 10 of the HVAC module should be connected to ground.
If those are all good then find the plug for the blower and make sure that it has power on pin one and ground (not just no volts but a solid ground reading) on pin 2. Pin 2 isn't connected directly to ground but connects through the blower motor speed control module. Pin 1 of that module should have a solid ground connection.
I don't see any connection between the heated seats and the blower system so they shouldn't affect each other.

Joe, I will try all of that and get back to you. A couple years ago my instrument cluster went bad, we didn’t know that was the problem, but I wasn’t able to turn on my heat or air, it was a similar problem, but completely different at the same time. Along with my air, my heated and cooled seats wouldn’t work. They told me at the dealer it was all connected. But they also told me it was my computer and it would cost me thousands for a replacement, when in fact it was my instrument cluster causing everything to go crazy 🙄😂
thank you for the advice, I’ll get back to you!

happy to report, it was none of the fuses or relays, but it was the resistor. It had a lose connection. Idk what the connection was with the trailer hookup, if any, but we are running cold again! Thanks for your help and suggestions!

I tried it on every setting, high, low, cold, hot. But happy to report it was just the resistor that had a loose connection. Feel silly now, but I didn’t even think of that lol.
