Here is the cycle time for the heaters from the Dodge manual.-
PREHEAT, BEFORE START CYCLE
Above 59 degrees F does not activate
18 degrees F to 59 degrees F Cycles for 10 seconds
1 degree F to 18 degree F Cycles for 15 seconds
-15 degres F to 0 degrees F Cycles for 17.5 seconds
below -15 degrees F Cycles for 20 seconds
POST HEAT, ENGINE RUNNING CYCLE?
Above 59 degrees F No
18 degrees F to 59 degrees F Yes
1 degree F to 18 degrees F Yes
-15 degrees F to 0 degrees F Yes
Below -15 degrees F Yes
I cannot find how long the post heat cycles are.
