  1. hello ,how many valves are per chamber on a 1998 cavalier ? Im changing the seals without removing the head and don't want any valves to fall in ,so i'm using hanging rope to fill the chambers

  2. My 04 sunfire gt is different from the one in the video can't figure out how to get the cover off to access the fan motor any ideas would be appreciated

  3. My fan is not blowing air as well as it used to. Replacing the resistor did fix my switch problem but not the weak air flow problem. Could this be a bad fan, ground wire, switch, or relay?

  4. I have a 1998 sunfire the a.c. blows go for awhile then it i slow down or speed up it will quit blowing just started doing it what could it be

  5. My blower motor stops blowing after a while (usually after 10 – 15 minutes). However if I give it a hard tap, it starts running at full blast again. Would this mean that my blower motor is dying and needs to be replaced?

  6. i have a 2002 sunfire that only blows cold air from the a/c while it's moving but when i'm stopped at a stop sign for example or sitting still idling it stops blowing cold air what can i do to fix this?

  7. well , my heater moter stops blowing after awhile but if i turn it off and on again it will work but stops after awhile , heater or the other thing ? any help guys would be much apreacted  

  8. I have a 2003 Chevy Cavalier and the blower motor has these like plastic rivets known as heat stakes what is the the easiest way of getting these off?

  9. It could be. You could turn the switch on, and test the power going to the blower motor with an ohm meter or a test light. If there's power to it, it may be the blower motor that has gone bad. Hope this helps you out. 888-844-3393

  10. HI Ken, Thanks for for visiting our channel on YouTube. We currently do not have an auto repair video on this particular repair. If you happen to have a Chiltons or a Haynes manual for your car it should be covered in there. We do carry a new blower motor for this vehicle with free shipping on our website 888-844-3393

  11. my heater just stopped working and after i seen this vid i went out to my cavy (angerly) smashed that motor with a coffee mug i had on the floor…and boom it worked again. thanks bro!

  12. If it's not green and doesn't smell like antifreeze you may have a clogged AC drain hose under the car. If this hose is clogged the AC water will build up in the system and eventually leak out on the passengerside. If you go under the car on the passengerside there will be a little drain hose hanging down (if you have AC) blow it out with some air, if it's clogged be debris water will come shooting out of it as the system drains. Hope this helps you out. 888-844-3393

  13. if you have something that seems like water leaking from behind that part that was just replaced in the video, is it coolant? it has no smell. on a 1997 Pontiac sunfire.

  14. If the housing is under the hood then it will make things a bit easier. There should be some sort of housing surrounding the motor so removing that will gain you access to the motor bolts.

  15. It may be the blower motor resistor that is going bad. Usually when they go bad you'll start to loose the heater speed settings as you are describing. We carry replacement blower motor resistors on our website Part Number: 1AACD00020 888-844-3393 Hope this helps you out.
