Having a bit of an annoying problem in 2 different areas:

1. Air suspension keeps trying to adjust when I start vehicle and then shows a fault stating "Normal Height Only". Any suggestions?

2. Brake interlock switch keeps sticking and locks up transmission. Should I get switch replaced or just try to lubricate it??

Thanks

 

diagnosis for the air suspension, and if the shifter won't shift then look at the shifter assembly for water damage along with rusted up shifter cable on the transmission.
