I have an '02 F150 XL. 200k miles. My a/c blows cold, and I have every fan speed, but it just doesn't blow very hard. I replaced the blower motor thinking that would work, but that did nothing. I've been told to clean the evaporator core, but I don't know where that is. How to do that, as well as any other part causing the problem.
View 14 RepliesI have google it looked all over was told it was under the hood next to the fan even shown a photo when I went under the hood right were the resistor was in the photo there was a long black box about 4 inches long and 2 inches wide. looked nothing like the photo.
So I went back on line and read that its above the passengers feet you take a few screws off after you take the glove box off and it should be there. Well after taking 8 screws off I find nothing but a coil behind there. Nothing that looked like a resistor.

I bought my youngest daughter a used 2009 Ford Escape (out of warranty) a week ago. Manual HVAC controls, 3.0 V6, AWD, 73K miles. The HVAC blower motor do not seem to move any air on speed 1 and 2. However speeds 3 and 4 appear to operate normally. Speed 4 noticeably puts out more volume of air then 3. Each 3 and 4 operator what seems to be normal speeds for their setting.
I would normally suspect resistor but my experience is usually that you have all or nothing not it's partially working like this is. I don't mind throwing a new resistor in there and trying it but I rather come up with a better way of troubleshooting it then throw parts at it.
I recently bought a 96 ranger.I noticed the fan did not work but for high. I search the internet and found how to remove it and discovered a mouse nest(village) which basically took over the housing where the evaportor core,blower motor resides. I bought a chilton but cannot remove the housing around the core so I cleaned it the best I could(air compressor and vacuum and disinfectant)...
I had to buy a new blower motor and resistor. However, I cannot find the hose that attached to the blower motor?-mouse had chewed a hole in the one- I've looked and found serveral differents names for it but seems I cannot find it at my local parts store.
My question is- is this intake hose? vent hose? I'm guessing I will have to go to dealer or, if I know the name I can look it up in a salvage yard?
My 2010 Expedition Limited AC seems to be stuck in the highest fan speed setting. Changing the setting on the panel control do nothing to change the speed. But you can adjust the temp and it will respond. It is a dual control unit. When I try to turn the system to off completely it will go to what I believe is the vents and stay on full blast. If I turn the truck off and on again the whole system remains off until I turn it on again. The only way to turn it completely off is to turn it to off mode and turn the truck off.

View 6 RepliesCurrently My AC / Heat blower motor operates but, speed 1 and 2 are the same, 3 and 4 are fine. I replaced the blower rheostat that is located on the firewall, but still no difference in fan speed.. A few years ago the blower only operated on Hi and the rheostat was the problem then.
View 3 RepliesI have and 07 F250 and the #2 speed for the blower motor don't work (hasn't since I bought it) I read that the most common cause of this is the resistor under the hood on the firewall so I replaced that and still no 2nd speed??? Where I look next? Motor itself maybe?
View 11 RepliesI replaced the blower motor resistor on a 2010 F150 with dual climate control where the blower was stuck on high.
After replacing the resistor, now the lower speeds work fine, but when placed on high speed, the fan completely shuts down. Replace with the old resistor, and it only runs on high.
How to proceed, or what else might be the problem?
Air Conditioner Blower Motor on any speed, lets say high. Running fine while driving. Come to a stop at idle or shift to N or P. A few seconds later the blower begins to vary its speed in pulsating rhythm in what would seem to be in cadence with what would be a rough or varying idle. Where to start? Is it the relay?

I have a 99 Olds Intrigue GLS. Going on 163k miles. She has been pretty good with the common fixes for this model. I decided to replace my upper and lower Coolant Hoses before I took a long trip. Everything went OK until I tried to use my AC later that day.
During my Coolant change out I did indeed start the car multiple times and eventually I disconnected the battery to reach a hose.
Now, when I turn on the AC, the Blower motor does not directly respond to my dash board speed control. The little bars indicating higher speed changes up and down as normal, but the blower doesn't change with it. Also, I can SOMETIMES get it to change speeds by turning the speed all the way up then back down a few clicks etc...Currently, when I turn on the car the AC does kick in under the hood, but the blower stays off.
Something fishy going on. I decided to disconnect the battery again and see if anything "reset". No Luck. I think it coincidental that it happened during my Coolant change out...

View 3 RepliesI'm looking to purchase an 04 f150 but this issue has been bugging me. What are the odds of the can phaser failing and destroying the 5.4 3v motor? I'd be really unhappy if I bought a truck only to have a pile of parts a few thousand miles down the road. I'm seriously considering just looking for a low mileage 01-03.
View 1 RepliesWell my blower motor only blows on high which IMO points to the resistor, went and bought one and still only blows on high. Tried to test the plug that goes to the resistor but couldn't get anything, shouldn't there be 12v going to the plug and then step down to the resistor until high is selected then 12v bypasses the resistor all together? Blows strong and cold, too cold actually since we cant turn the blower down so we have to turn it off for a few minutes.
View 9 RepliesI have a Full Size 93, 5.8L Van. The blower motor has stopped working. I have checked the fuzes, ok. I have checked the Power Distrubution Box, ok. I do have power to my Aux (rear) blower. I have hot wired my blower motor, it works. I have no power to the blower motor, thermal limiter, or to the fan control switch on the dash. (Like I said, the Aux on the dash works). What else is there?
View 14 RepliesMy 92 F-150 my heater blower motor doesn't put out enough air like my 2003 Lightning blower motor does.... So I figured after all these years that I would put a new heater blower motor in, well it's the same hear output and there's no debris in the heating ducts and the cable lever is working fine to close the blend door, so I guess maybe it's normal for these 92-96 F-150 trucks to have mediocre heating output ;-( Is there a bigger motor I could put in to get more heat..... The resistor is fine to, it works on all speeds.....

The front heater/AC blower motor only works when it wants to. It starts very intermittently and then shuts off then you go down the road a little more and it comes back on, it will do the same thing sitting in the driveway just idling. There is no timing it, it just turns on when it wants to and then back off again.
I checked the fuses and the fuses are fine. The blower motor when hooked up directly to the battery blows fine. When it isnt working of course there is no juice going to the blower motor through the hotwire of the blower motor, I have checked this with my volt meter.
I did replace the switch that turns the blower on in the dahs, and it didnt do the trick.
I'm looking for information and possible photo location for the blower motor resistor. My truck has climate control. I've looked under the dash on the passenger side and behind the glove box door and I've been unable to spot the location. Do I have to remove the plastic panel behind the glove box?

View 1 RepliesHave a 2009 platinum, 5.4, supercrew with dualzone heating and air. The blower motor resistor block is overheating and melting the connector block. fooled with it way too much, and then put a new resistor and pigtail in it. The new resistor would kick out in about 30 seconds, so used the old resistor on the new pigtail, got hot, melted the new pigtail. What is causing the resistor block to get so hot, and what do I do about it?
View 7 RepliesI'm having some trouble with the front blower fan on my 97 Aerostar 3.0, it will only intermittently work, one time we had it running, lifted up the hood on the van, checked the connection to the motor, looked good, dropped the hood and the fan immediately started working again, I'm wonder if the relay might be starting to go bad, the fan in the back works, so I'm not sure. Where the relay is for the blower motor, or what might be wrong?
