This video shows my little ‘adventure’ as I repair the blower motor on this 2004 Mercury Grand Marquis. The Grand Marquis is pretty much the same as the Ford Crown Victoria or full sized Lincoln. I did end up fixing it in the end but it took a little bit to get to the bottom of the problem. I’ll admit that was my own doing but all’s well that ends well I suppose. There is another version of this video that goes into more detail available to Premium Members of EricTheCarGuy.com.

I have Marquis 2007 and He only blow air by the froth glass and cant change in the front or feets doesnt change I did replace the actuator all fuse are good air blower works now I dont know what else I can do
Thanks bro, I appreciate the knowledge. I wondered why the switch harness melted in the first place. Thanks for letting us know you’re human. 😀
Was the switch the only problem from the very beginning?
Thanks for your scientific test to see if it will work, drove 45 min with no air in 20° weather in south Louisiana got to work tried it had full blast air again ! If it gets me ubtill I can get a new one it works !!! Thanks
Heck with the haters, this video actually helped me troubleshoot a lot of stuff. Thank you.
I flushed out my heater core and replace the heater resistor. But i still cant get any heat do u think it might be the blower motor? I do have cold ac.
Ignore negative comments,. You are very helpful to DIY individuals .
"CV /GM has been around since they started making Fords" LOL
ERIC U DIDN'T HAVE TO SHOW THIS VIDEO. I LEARNED FROM IT. VERY COOL. San Antonio tx
I would replace the switch! and agree the motor was drawing to many AMPS. But I give you allot of credit for admitting your mistake. good for you.
This was very helpful for my Dads Grand Marquis and for my Marauder. Thank you! Saved us at least $300 between both cars!
At the beginning when you are testing the blower motor, I see you have the knob on the right turned off. My blower motor doesn't work unless the one on the right is turned on to one of the settings, i.e. vent, norm ac, max ac, defrost, etc.
A good Mechanic no matter how long you have worked still runs into issues right in front of them. It's only the the ones that think they know whats wrong and are can't admit it. You my friend may of had a bad day but in my 35 years of working on just about everything your truthfulness is worth gold to me.
what about if you have everything but HIGH SPEED? and no air through vents only floor and dash. 1998 buick lesabre
thanks!
Thanks for the ride Eric! I will be putting mine in next week. Great help
im willing to bet the old motor blower still worked lol
Thank you so much Eric another great video Lessons Learned Awesome!!! Thank you!!! For including us in this journey.
Sir I am having problems with my crown vic 2011 model when I put key in ignition switch and turn to accessory mode my blower motor turn on in full speed and stay on what will cause for this please help are any one there
Nice one
All my speeds work. AC works. The problem is the heat doesn't stay hot and i tried it on all the different functions, floor, vent, mix , defroster, i.e. it initially warm when first turned on but heat doesn't stay 2 minutes later. What's my diagnosis
My switches are touch not knobs on my 2004 Grand Marquis
Thank you Eric the car guy. Replaced the blower motor and all is well.
That was pretty cool.
