@nellb you are not telling us if it blinks continuous or if there is a pattern to it. Normally that light blinks because it failed a self test. The HVAC went into diagnostics mode. Something like a failed blend door actuator etc. can cause that. The best thing to do would be to get your Caravan scanned and see what code it gives you.
