What have you checked so far ?
Could be the blower motor, the resistor, a fuse, bad ground connection, or the HVAC controller if you have climate control.

SOURCE: Air conditioner/heater blower fan on 1997 Buick

it will be hard to diagnose with out having my hands on it but try this.

this vehicle is known for blower motor resistor failure.

under the dash on the passenger side next to the blower motor there is a resistor attatched to the blower motor case it will have a single plug with 5 or 6 wires in it, they are normally within a couple of inches of the blower motor, remove this resistor and look at closely for any signs of burning this is a common problem, you can buy one at any parts house, do not operate the motor with the resistor removed from its mounting hole or you will damage it.

if the resistor looks good than purchase you a test light and drop me a line and i will explain how to test the entire system its not hard to do.

SOURCE: 2001 buick lesabre. my heater and a/c blower is not working

I believed the a/c blower is a relay activated. So no fuse getting blown to make it to go bad. Try to locate such relay (the ID label is found inside the relay cover assembly). Swap it with an identical one before making a trip to auto part store.

SOURCE: 1997 buick lesabre HEATER PROBLEMS The fan

This could be several things. First I would check that the thermostat is not stuck open. This will condition will make the car run cold when it is cold outside.

If this is not the case........and I'm assuming you've already checked that the antifreeze is full, make sure that the heater valve is working. If it is frozen in place then it won't move and won't allow the warm water to circulate through the heater core.

I'm basing my answers on a standard Lesabre. Yours may not have the standard climate control.

Freightliner columbia wont blow heat into cab have replaced thermostats and heater core blend doors work heater core gets hot and blower works but air from vents only gets to 80 deg


The air from the heater core will be as hot as the coolant temperature of the engine. 80 Degrees is the opening temperature of the thermostat and that will be where it remains until the engine starts to work or the ambient temperature rises.
Thermostats come in a couple of different opening temperatures so check around for one that opens around 85 degrees if you want hotter air in the cab
Another point is to close the recirculating vent door to the cabin as the heater core is trying to heat fresh freezing air if it is open

2002 mountaineer heater works, but won't blow out of the top vents that. The bottom vents work fine.


Unfortunately you are going to have to remove the dash to fix this problem. What has happened can be one of two things. The first is the ductwork has become unattached leading to the top vents. The second possibility is a damper is not working. With the engine off and the switch on, put the selector to defrost while listening closely. You should hear dampers opening and closing. If you don't, that may be the problem. They are either electrically controlled or operate off of vacuum. Hope this helps

Run self test on heater control head 1999 grand marquis


sounds like maybe your dryer is plugged up .
follow the cold line with your hand .
or its working and the vent flapper is disconnected .
its the one that's tied to the front buttons / lever on front panel.
you should hear it switch between cold an hot as the flap closes opens. it will be definitely heard. it sucks vacuum an plops close/open.
more than likely you have a loose bad vacuum line/lever in dash.

I have a 2004 kia optima and i have no heat. checked all the fuses and all good but still dosen't blow heat.


do you mean the heater isnt giving hot air or the blower motor doesnt work if you have no heat check prestone level in rad possible thermostat not working rad cap leaking pressure inside car vent not closing or opening is this a fully electric heater control or manual type with cables what i mean do you push a button forr heat or turn a knob on the heater if it is a knob its manual type and the cables run to your feet on the passenger side sometimes they pop out and the control stays at the last position or if push button type electric the heater control burns you have to take the control off to see if not burnt but for know check the traps are closing and opening

Blower is working but no heat


there are 2 things right off the bat I need you to check. first is to warm up the truck, and turn the heater on. check the hoses going to the heater core. is one getting hot? if not, then follow it back by the engine and you will see a valve with some wiring. that's the heater control valve. it may be stuck shut. try replacing that. if the line is getting hot, then you may have a clogged or damaged heater core. that is under the dash on the passenger side. also check to make sure the vent system is opening at the heater core. this works off of vacuum(little rubber lines. it may also be stuck, you should be able to hear it open and close when you turn the control to heat and back. hope this helps. let me know if this isn't it, and we'll try something else

I am not getting heat all the time into my 1990 Maxima I flushed the system and replaced the engine themostate. Water flows threw the heater coil. What is next?


There are 2 thing is can think of right off the bat. Is the blower motor working? If your heater core and heater valve are working, is your duct valves working? They open and close using the car vacuum. When you shift your control to heat, you should hear the duct open or close. allowing only heat from the heater core. You may have a bad actuator valve or a leaking vacuum hose. That's all I can think of right now, hope this helps

Getting heat in the heater core,heater door are opening, but no heat coming out the vents,help thanks


It sounds like the blower motor is not working. If you don't hear it running when you switch it on, check the fuse first. If the fuse is OK, you will probably need a new blower motor. It could also be a faulty fan switch or blower motor resistor. Once you remove the blower motor assembly, you can test it by putting battery voltage across the contacts with jumper wires, making sure to get correct polarity. If it does not spin, it should be replaced. If the blower does work when removed, the fan switch is probably at fault. The resistor is usually indicated when the fan works only at certain switch positions, but not all.

A/C works fine, the blower's fine, replaced thermostat, no heat.


If you don't hear a thud or noise of a flap opening or closing when switching between hot and cold then a lever is probably broken.
