PART NUMBER INFORMATION
*******************************************************************
The part number is: 27761-70T03 Module Assy-Pow
It is officially called an AC Blower Amplifier.

It cost me $153.32 + tax (not concerned about getting the best price since having the fan on high all the time drove my wife nuts for the two days it was acting up!)

One other suggestion... you're gonna have to take apart the glovebox door and compartment behind it (easy enough). While back there, change out the cabin filter (another Nissan item) since you will have everything apart anyway. Kill two birds with one stone. That thing (if equipped, gets really nasty).

SOURCE: Heat/AC Blower fan speed only works on High

Alot of people have the same problem with the fan switch and blown bulbs. There really is no fix for this. Jeep really screwed up when designing the heater control assembly. The cheapest solution is to buy another unit off Ebay. Can always go to the dealer but be ready to PAY for there mistakes.

SOURCE: both hoses to heater core are hot, blender door

if the air is definatly being blown through the heater core , then the core is blocked.if there is no hot coolant passing through the core then ------no warm air ---give it a good look see if you can see the deflector guiding the blown air is going far enough to send majority of air through heater good luck

SOURCE: heater only blows Very luke

Read all of these instructions before starting this job.
First test your heater core for flow by disconnecting both heater core hoses from motor and forcing air from an air compressor into one of them watching for flow from the other. If you have no flow then you may need to backflush your heater core - it is possible you have blockage in it. Your local auto parts store has a backflush kit you can buy that will have a backflush valve ( to be added to your supply heater core hose ) and an additive to put in your coolant system. The kit will not include new coolant so you will need to get that too. Install valve and connect a garden hose.Run motor specified time in the kit. Remove lower hose from your radiator and turn on the water from the hose full blast. Watch the coolant coming out from your radiator to see if any chunky stuff comes out - also watch for the color of the flow. Run water until it comes out clear, then shut off water and disconnect garden hose. Allow system to drain, reconnect radiator hose and cap flush valve. Refill coolant system, turn heat on high and run motor until it is warm. Top off coolant in radiator ( be careful - the pressure may cause coolant to spray out when you remove cap - put a rag over the cap before you remove slowly). If you do not have warm air at this point you may have a bubble in the heater core and may need to block rear wheels then raise the front of the vehicle until the radiator cap is higher than the heater core. Restart vehicle and turn heater on high . Check coolant level in radiator and top off, then cap radiator and shut off motor. Lower vehicle and start again with heater on high. If you still have no heat then your heater core may be plugged. To check, remove both heater hoses from motor and force air from an air compressor into one of the hoses, watching for flow from the other hose - if no flow then core is plugged and needs to be replaced, but if you have flow then you still have an air bubble in the system and need to purge using the above steps until you have heat.
Hope this helps and please rate my solution - good luck!!

Rear blower: only works on high when set on cold, won't work at all when set to heat


I would start with the rear blower motor resistor, the resistor is what controls the speed of the fan, the resistor is located in the rear heater box near the blower, you will need to remove the right rear side panel to access the heater box. start with that

Still waiting for an answer about my Chrysler 2002 Town & country. QUESTION : Fan won't blow when car is ideling will start after I start driving again.


I would need more info to give any advice.
I assume you mean the blower for the ac and heater.
How is it not working but works on high ?
And what power are you turning off that makes it blow harder ?

What's your problem?I have a 1996 Chevrolet Suburban. The AC is blowing out hot air. I have had the truck for 6 years, every Summer its the same thing. The ac does not get cold, I take it to the m


To clarify - - if the truck has rear and heat, you have two heater cores and two evaporator cores. The evap cores carry the freon.
If the leak is in the evap core in the front, the price is probably right.

Ac compressort had to be replaced because it seized up. AC ran good for 2 weeks then went out, now the heater doesnt want to work half the time. i dont know if its my heater coil, a leak in my ac lines,...


THE BLEND DOOR THAT CONTROLS HOT TO COLD SWITCHING IS STICKING. THE CONTORL HEAD IS ELECTRIC AND MAY BE CAUSING THE PROBLEM. HEAT AND AC ARE 2 COMPLETELY DIFFERENT SYSTEMS EXCEPT FOR THE CONTROLLER UNDER YOUR RADIO. HEATER COIL IS REALLY A HEATER CORE WHICH IS A LITTLE RADIATOR INSIDE THE CAR BEHIND THE DASHBOARD.
