Having problems with your 2006 Chevrolet HHR ?
How do i put more antifreeze on my hhr
\015 My 2006 chevy hhr fan keeps running even when i turn it off\015
How long does it run after shut off?Does it shut off at all or just run forever? If it ends up shuting off at some point after shut off, then I wouldnt worry to much bout it. The fan will run until the temperature sensor tells the computer that your engine is cool enough whether car is off or not. If it never shuts off then that'd be different : ) can honestly say I haven't seen that b4 but I'd say start at the temp sensor chk for voltage readings and see if they are within specs for your vehicle. Maybe sending constant signal to computer. Hope this helps you out.
