viper 5901 on nissan altima

installed the viper 5901 on  a 2008 nissan atilma and used a DLPK Immoblizer and doorlock bypass the car starts but, A?C doesn't work and when the car is started the radio radio display comes on and goes off but the radio still plays. Everything was connected according to the manual and everything is getting power. Does anybody know why it's causing this pronlem?Norris04

ill would start by checking your 3rd acc pin 48 yellow and red wire at the fuse box under the hood if not power would not turn on your AC also regarding the lights Its normal because your only powering the exterior light the actual parking lights so when they flash they would the interior when there off but would go out when there on
