99 3.3 Immobiliser Problem - AHawkins30
Hi

My 3.3l Grand LE cut out while driving and the alarm set light came on. Now whenever I try to start it there is no crank and it will not attempt to turn over. The alarm set light flashes and the car beeps 16 times and then the alarm set light stays on. I have tried the fixes in other posts supplied by MerlinTec but they don't seem to help it. I have checked the heater control unit at it seems ok but then checked the plug on the wiring harness for the 21 pin connection. The plastic casing around pin 21 shows signs of melting and appears to have melted almost through to pin 20. When I try to plug this back in the car makes a noise near the passenger side footwell almost like a small motor running. Can anyone help as Chrysler doesn't seem to want to know at all. If I replace the harness will solve the problem? Please help as car has been off the road for 8 weeks already.

Thanks

Anthony
