Heat and ac blower sound normal but very little air is moving inside the cabin. What can cause this?


Cabin air filter? Blower motor working on all speeds? Critters building nest in heater box

Why must I run the defroster so much?


this could be two items that i can think of
1st could be a stopped up cabin air filter , a low air flow would be felt out the vents on blower high setting

2nd sometimes a small hole develops in your heater core allowing a tiny bit of your cars coolant to flow into heat chamber , this gets evaporated by air flow thru heat box and recondenses back inside car , telltale signs are stuffy smell inside car and slight drip of coolant on ground under car as problem persists

heater core replacment is needed to fix this problem

Little heat coming out of vents.


IF YOU CAN'T FEEL THE AIR FLOW OUT BUT YOU HEAR THE BLOWER MOTOR WORKING, BEHIND THE GLOVE BOX IS A CABIN FILTER.REPLACE FILTER
IF YOU HAVE GOOD AIR FLOW BUT NO HEAT:
1;VACUUM LEAKING TO HEATER CONTROL
2;WATER PUMP GOING BAD / NOT CIRCULATING COOLANT,HIGH RPM/MORE COOLANT TO THE HEATER CORE
3;OPEN THERMOSTAT/ENGINE TEMPERATURE TO LOW
1;CHANGE THE DIRECTION FROM VENTS TO FLOUR TO WINDSHIELD. IF NOTHING HAPPEN IS THE VACUUM
2;RUN THE ENGINE INSIDE ON WARM PLACE ON IDLE.NOTE THE GAUGE IF PAS 1/2 TO 3/4. IF PAS 3/4 MARK REPLACE WATER PUMP
3;IF GAUGE STAY BELOW 1/2 REPLACE THERMOSTAT
GOOD LUCK

Where is the small blower the samples the air insie the cabin on a 93 Mercedes 2.8 this is the part # 0008301908 its about 3 inches long and its not the same as the primary blow motor underneath the...


Under the dash . Remove the glove box to see it. It is the sampling fan that blows cabin air past a temperature sensor to allow the automatic heating system HVAC to keep temperature you set, steady.

The HVAC will work just fine without it although you may have to fine tune the temperature setting from time to time.

Heat or AC come on but fan will not blow.....


I would say either the blower motor is not running, or the blend door is not opening to let the air thru the system.
Someone would need to verify the blower motor is running then check for a dirty cabin air filter or a stuck blend door.

I noticed when it rains passenger side floor gets wet check for leaks from windshield no leaks. then i noticed a strange sound when i turn the heat on. now heat doesn't work at all


I have seen some problems with water coming in through the cabin air filter. (Also known as passenger compartment air filter - see picture) Sometimes this is caused by a buildup of leaves and debris in the cowl area that causes water to overflow into the filter area. Sometimes this is caused by the filter not being installed correctly. I have even seen the water diverter that goes over the top of the filter get discarded by quick-lube "specialists". Anyway, these conditions will allow water to enter into the vehicle through the heater system. Many times I have seen the filter so badly damaged by water and debris that it ends up in the blower motor and stops it from running. This is where I would look for the problem first.

Cooling system problems include low coolant and an acrid smell coming through the vents. We filled up the coolant and checked for leaks and there are none. Will this happen again and what is going on.


Do the windows (windshield) fog up for about 2 seconds if you switch the defroster on too? Sounds like you have a leak in the heater core. It's a small radiator located in the heater box inside the cabin of the vehicle. The blower fan blows through it to heat the cabin. If it's leaking or has a hole in it, what you are smelling is antifreeze. You can try a good radiator sealant and if that doesn't work. You'll have to change the heater core. Explorers aren't fun.
