I need help here guys, I have a Clifford Avantguard 5 installed on a 2000 GMC Sierra, When I drive my truck, and only when the truck has been driven, and the weather is .82F and above, after I park, I have to wait 15 t0 30 mins to arm the system otherwise it will go off constantly every 3 mins up to 3 to 5 times, this is a very rare and annoying thing during the summer months. This problem never occurs in cooler weather 80 and below, never! I been dealing with this agony for the last 3 yrs...My proximity sensor is not connected, I completely took it off when I started having these problems....Any ideas? Please help!
