2003 Rendezvous, alarm/remote start

You say you re-checked connections, how did you do this?  Visually or with a test light or meter?  If you used a ScotchLock type piercing wire tap on the park light circuit then it may have severed the wire and you wouldn't be able to see it through the connector.

I would suggest back-probing with a low current test light or DVOM at the module connector.  Look for a ground pulse if you are using the low current (-) output or a B+ pulse if you are using the (+) output.  If no pulse there, check for a blown fuse in one of the power leads to the alarm module.  One of them may be dedicated to powering the parking light (+) circuit.  If that is all OK then I would suggest a failed driver or micro relay (whichever is used in your design) inside the module.  If you do have pulses at the module I would suggest a broken connection where you grabbed the park light circuit.

Good luck,

Tony

now i have another problem, the unlock system is not working i can only lock but i can't unlock, may be because i used a relay and a resistror to lock the doors but to unlock i connected it directly, do you thinl that i have to add a relay to unlock too?
