My 2011 hhr , the inside fan has developed a problem , when i start the car the fan won't work then after I start driving the fan will start working, then it stays working then after I turn the car off and park and start the car again sometimes but not all the time the fan won't work till I drive for awhile .

 

check your fuses or relay.

 

Is it making any noise? Have you checked the cabin air filter (directions in your Owner Manual)(Owner Manual available thru the link in my sig).

 

Hi,thank you I have checked the fuses all seem okay , where is the relay located? Thanks for your help .

 

Hi,not making any noise , I pulled the cabin filter a short time ago and cleaned it ! Thanks for your help .

 

Relay #30, interior fuse block. Just for clarity, you've checked fuses #10 and #16 in the interior fuse block. And fuses #9(diode) and #22 underhood? It's probably not the underhood items, but it doesn't hurt to check.

 

The fact that it does run after he drives it for awhile would pretty much rule out fuses as being the problem. Wouldn't it?

 

They could be loose.

 

My extra long sight says it must be the fan motor dying. Sounds exactly like when one of my floor fans decides it needed to be lubricated 3,000 hours ago.

 

It's bored likes to go for a drive before it perks up. After you have inspected all connections, fuses , grounds. Check for voltage at the fan connection, but I'm think replacement of the fan motor is eminent.
