This negative door trigger circuit was built and installed and it worked great for several months. Lately, however the accessory power is slow to activate after the car has been started. Sometimes it comes on right away but most of the time it can take 5 or 10 minutes before I can use the radio. Seems one of the 3 relays is slow to actuate. Any ideas about what would cause this problem would be most appreciated as it can help me fix the problem without a lot of testing and trial & error.

The car is a 1999 Nissan Maxima.

Faulty connection(s) or faulty relay(s). My money is on one or more faulty connections.

Look at ignition switch and fuse box connections, that is trace back the radio pathway or anything else on that ACC circuit such as your wipers. If it's only the radio, it might just be a poor power supply in the actual radio.
Incidentally, what's the connection between negative door trigger and ACC power?
Except in the case of RAP, or aftermarket alarm one has nothing to do with the other or are we not being told everything?

Read the installation manual, do a search here or online for your vehicle wiring before posting.

Thank you. Poor crimps in the spade connectors caused the intermittent connection problems. I soldered each crimp to make sure this doesn't happen again.
