I have been trying to get smoke to work but with no luck. Does anyone have any advice? Please and thank you. I did add smoke fluid and ran the cycle 10’ times also.

The most likely thing I'd guess at is a burnt wick. Adding fluid doesn't work, if it's fully burnt. The fluid doesn't get around the elements where it needs to be.
After that, something went south.
I have to open mine up as well. It worked after I last fixed it. Now it doesn't. I believe it goes thru a lot of fluid!
Looks like 4 screws in recesses under the station let that building come off. The center clear section just snaps in. Flip the station over to where the middle clear section was and remove the smoke unit.
I'll take pics.
Mine has the impeller on the smoke engine stuck. It's not turning. My smoke wick still looks great. I changed it maybe 2 years back?
I applied 3 volts DC to the smoke fan and can hear it run. Yet the blade does not turn?
well? not in order but the pics may help you?
Now I have a loose impeller to fix!
There's the smallest imperfection in the round at the bottom of the impeller. It hits the housing and stops it. Make sure yours spins freely.
IMO the whole smoke tube exhaust, should have been installed inside the clear part of the building. It just flows slightly out the door on mine now. Maybe when it produces more smoke, the effect will be better?
There also was a kink in the rubber tube inside that I tried to fix. That probably limits the smoke volume.

Perfect thank you for all the help, weekend project for me when the snow comes in!!!
I meant to ask were is the best place to get replacement wicks? Also if needed a replacement smoke unit also? Thank you
Most techs would have the whole smoke unit, maybe???
The wicks too. Some people use tiki wicks and strip them down for pieces. They have a rough outside coating.
I had this working then it stopped. fixed it. and then it stopped. fixed it again. and then..... it stopped?
Seems like the impeller is made of some soft material that grows when it gets hot. So when it grows, the fan can't spin.
Not like a normal MTH smoke impeller material? 
I know bad design, thank you and good luck getting yours running.
I replaced the fan assembly at first, thinking that was best. Of course, that left me with a sinking feeling that I didn't fix it correctly and wrecked another spare smoke unit I have for future use.
So I went back inside and removed it. I took the stock fan impeller and filed it down less than 1/16" all around. I noticed that regular smoke impellers have more space around them in the housing. So I believe this impeller is oversized. It's such a tight fit that any imperfection causes it to rub. I have to believe that the material it's made from, somehow swelled up?
I dabbed some loctite inside and will know tomorrow how it works. Hopefully, I didn't glue the motor!
I bought the car wash went it first came out. From day one, I never thought the smoke effect was very effective. In addition to not producing enough smoke, I found it to be very temperamental requiring the exact amount of fluid to smoke correctly. Too much or too little fluid would produce no smoke at all. The rest of the car wash functionality works fine but I never believed it was a top priority to fix the smoke unit given all the other kinetic accessories on the layout.
Thank you for putting it into perspective for me.
