See that huge long black thing under your console, with all the air vents and colored plastic vacum lines attahed. It's in there, on the passenger side. Yep, the whole darn thing has to come out. They claim the console doesn't have to be removed; you cut a section out by the glovebox, but don't believe it (if you have the convertable) There is steel bracing in the center console which will 'catch' it a you try and slide it out.
I replaced mine and only have 5 left over parts! Not bad for a rookie. Worst job I ever had.
Probably the blower motor resistor is shot.
The most common cause of the heater blower being on high only is the blower resister failing. The second most common problem is the blower switch going bad.
Heater blower relay if there is one... There are relays underneathe steering wheel but right next to driver door. And in engine compartment where shock is on drivers side.
The blower resistor is located behind the dashboard. It is found behind the heater near the center of the vehicle.
If yourtalking about the heater blower, I believe they are hidden behind the glove box inner liner.
Most likely and bad blower motor resistor.
Remove the wiring harness from the back of your 2005 Chevy Cavalier heater blower motor. Remove the heater blower motor retaining bolts. Remove the heater blower fan.
probably the heater core is plugged
in another post, it says it is behind the glove box...take it out, and it should be right there.
Thermostat possibly stuck open or heater control valve broken. Now if you mean the blower motor has stopped working, check the fuse, blower motor itself, or the blower motor resistor pack.
The fuel pump on a 1992 Chrysler LeBaron is inside the fuel tank.
If the blower is good then the problem is coolant. Something is stopping the warm coolant from the engine from reaching the heater core inside the car. This might be thermostat, heater control valve, blocked heater hose or a blocked heater core. I would suggest letting the car warm up and checking the heater hoses (2) by hand to see where the hot water stops. If there is no hot water at all it is probably a thermostat problem.
