[A/S] Tag Axle Compressor Electrial Failure

["chris&mare girdwood" <cmgirdwood@xxxxxxxxxxx>]

I have a 1985 Airstream 345 motorhome. As I was driving home to put it in 
storage, the low air light came on and the compressor did not. Also, the 
driver's and passenger's power seat controls were dead. Are they on the same 
curcuit? If they are, what and where should I look? Thank you in advance for 
any help!
