hey folks. I have a 2006 HHR. lastnight we had a lot of rain and Im sure its related to it.
My blower fan turns on, all speeds. sounds fine. but nothing is coming out of the vents. I tried all settings of vents but nothing. any ideas??

 

Possibly water's leaked in and clogged the cabin filter. If so, fix the butyl patch area. to fix the leak and replace the filter.

 

Seems like it could be the mode cam or the air inlet actuator.They're located on the heater module.

 

now, it wont start. turn the key and accessories come on,but doesnt turn over. I can use the factory remote start. it starts the car. I put the key in and turn "on", the engine shuts off. did that a couple times, now that doesnt work.
we had alot of rain/wind lastnight. the floor is wet under the blower assy. fuse box is dry.
Im at the Dealers now. keep the suggestions coming and I will give the solution...hopefully soon!

 

Pitbull76 was correct on the cabin filter. The not starting was a problem with the Keys security. It had to be relearned...
Dont know why two different things had to happen together!.Luck I guess.
Thanks for the help! hopefully this will help out someone in the future.

 

Thanks for the update, it's good to get final resolutions for our knowledge base.
