1998 Chevrolet 3500

Somewhere there is a problem with air delivery to the vents, the blower is on high and there is little or no air coming out, didn't see leaks anywhere and I cleaned the evaporator coil with coil clean. I also noticed that the heater core is hot, like there it is not being isolated for some reason. This is a 1998 Chevrolet 3500 with a 6.5l diesel.

I would try replacing the control unit, they are prone to fail.

Ac controller works blower works little air coming House of vent in the red light the heater lights on


Just because the Blower works doesn't mean you will get air delivery. If the Blower is working but the Blower FAN is not spinning you will get no air delivery. Check out this video to learn more about the blower unit. https://www.youtube.com/watch?v=VpYX663B7Mc

2004 Dodge Ram 3500 Turbo Cummins diesel, air conditioning is cold but there is very little air pressure even when turned on high, fan sounds like it is blowing like crazy but very little air movement...


Sounds like the "Blend Doors" are not completely closed (or opened). The Blend Doors open and close to direct the air from the blower motor to the vent selection you have made on the control panel (defrost on windshield, floor, front, etc) You may need to try various selections to see if the blend doors actually open or close. If no changes, it could be a blend door actuator failing.

Replaced blower motor and resistor on my 1998 oldsmobilehardly no


If the blower motor is capable of working on all the speeds but you only get wisp of air out of the vents then the fan side of the evaporator core for the a/c may be coated with crud and debris which is restricting most of the air that the blower is moving. Usually this problem comes on fairly slowly until one day it is realized that hardly any air is coming out of any of the vents even with the blower on high speed. The blower may even sound like it is working harder than it should to create this little bit of airflow. The fix for this is to remove the blower motor and look into the plastic air plenum with a mirror or flexible borescope and check the a/c evaporator for a thin coating of gray crud. If it's present then I use compressed air and a long blow nozzle [bent to get close to the core] and blow the crud loose. You may not get it all but usually you can blow out enough of it to get back 90% of your airflow. If however your blower doesn't work on every speed then you may have other electrical issues that are preventing the blower from reaching full speed.

Very little air when air conditioner is on


I took mine to the dealer and they found a plastic back hand been sucked up into where the blower pulls air in by the passenger feet.. Good luck. Dealer charged $75.00 to pull it out.
