will77530 Posted January 9, 2010 Report Share Posted January 9, 2010 i may be wrong but. if your car is just idleing the engine isnt putting off much heat so there is no heat for your heater to work. get a second opinion though. Quote Link to comment Share on other sites More sharing options...
BigPimpin91 Posted January 9, 2010 Report Share Posted January 9, 2010 If you're up to operating temp and heat is poor at idle it may be a number of issues. Rev to a steady 2k and see if it changes. Check coolant level. Do a heater core flush. Quote BigPimpin91's Banging Music Link to comment Share on other sites More sharing options...
__d_a_v_i_d__ Posted January 9, 2010 Report Share Posted January 9, 2010 my car works the same running or parked. but it has to be fully warmed up, when i first start it in the morning, its cold as hell. all cars do that. dont know if its already warm up and still does that tho Quote Chevy Impala Shocker Sigs / TC Sounds 12s Sundown NS-1 | SAX 100.4 Sundown Neos | Dayton Audio Neos ETCCC ETCCC ETCCC My YouTube ---- Subcribe!!

BigPimpin91 Posted January 9, 2010 Report Share Posted January 9, 2010 if i rev it usually goes back to heat. Might be low on coolant. Check that. Quote BigPimpin91's Banging Music Link to comment Share on other sites More sharing options...
wildbeast15 Posted January 9, 2010 Report Share Posted January 9, 2010 coolant could be low... Thermostat on those goes ALL the time.. so does the hearter core on those.. along with the sensors.. could also be a kink in the hose and when the engine rocks at higher rpm's it unkinks (yes it has happened before) Quote The set up your talking about would sound great in my Tahoe. Trade you my dog for it. He has one eye but that only makes for bad depth perception so hey so what if he is running into shit, look at it this way he is easy to sneak up ninja style on.
