viper 5301, 1999 subaru outback

Viper 5301 no auto defogger below 55, but I can turn it on with the remote (func x 4, start). So, the 5301 can turn it on, just doesn't do it below 55 automatically. I have started car when it is 25 degrees out and it still doesn't turn on the defroster automatically - I am reasonably sure it was <55 in the car. I've looked over the owner's manual, programming stuff in install manual - can't figure this one out. Viper 5301 1999 Subaru Legacy Outback Thanks, Wally

Have you tried to change Menu 3. Item 11 to latched or Pulse and see what happens?  How is the remote starter connected to your rear window defroster?When all else fails, Read the Instructions

Yes, well, I set it to pulsed. It connects to the defogger timer. It basically performs the same function as the momentary switch that turns the defogger on - it grounds it momentarily. Again, I can turn the defogger on with the remote by pressing f button 4 times and then the remote start button. So the 5301 can turn the defogger on with no problem. It just doesn't do it automatically when it is below 55F in the car - which is what it looks like it is supposed to do. I could not find anything programming-wise that affects that part of the function. Thanks, Wally

That is kind of puzzeling? I have three 5301 in my vehicles here and the all come on automatically.  One is pulsed from the dash button, 2000 taurus, and one is through a relay right to the wire in the drivers sill, bypassing the dash button, 1998 Cavalier.  My wifes car, I don't know. I did not do that install.

All three work as they should when below 55 degrees. maybe your 5301 has a defect. 

Anyone else have a thought??

I guess it just wasn't cold enough where the unit was located. The last 2 times I've gotten in the car after remote starting, the defroster has been on. Thanks, Wally
