I washed my 2006 Toyota Tacoma truck yesterday. Everything was fine driving it before I washed it. I tried to back it out of my parking spot today and it will not move. It feels like it is trying to move but something it holding it place. I did smell something burning but I figured that was the engine attempting to move but was unable. Is one of my brakes seized up from getting wet and then not driving it? Is it something else? I am not very mechanical and have very little in my tool chest so try to be simple in your answers.
If it was a siezed wheel, the car would still go, and just drag the wheel. Does the engine rev up when you step on the gas, or sound like it is laboring?
Brakes can seize up but I’ve never seen it happen overnight. Usually it takes a few months of sitting out in the elements.
Try putting the parking brake / emergency brake on as hard as you can then letting it off and repeat that a few times. Maybe the parking brake got stuck. Also, just try stomping on the brakes a few times. See if that breaks anything loose.
The engine gets bogged down when I let the clutch out.
The engine would rev up when I pressed on the gas. I tried setting the parking brake several times but that did nothing. I then pushed down hard on the brake pedal several times and I heard a pop then a release of the car and now it is not stuck. Problem solved but what was my problem?
It could still be a sticky parking brake cable …
It could be a sticky front caliper …
It could be something broke in the rear drums …
For sure, though, take it to a brake shop … be on the safe side … and do this right away … do not pass go … do not collect $200 … get this looked at as soon as you can …
If it drove home fine and the last thing you did was put the parking brake on then it’s likely a stuck parking brake cable.
It’s a simple test, put it in neutral and see if you can push the vehicle (make sure it’s on a level surface.
I’m going with seized brake shoe on the rear drum brakes - my wife’s car used to do this in damp weather because it had to be parked on a slope, so the handbrake would be pulled tighter than if it was parked on the flat - if left for 24 hours, the shoe would bind to the inside of the drum (rust maybe?).
A few gentle attempts to drive it forward, then back, then forward, would usually result in a loud clunk as the shoe broke free.
However, this was an indicator of other problems with the brakes (in our case, the protective covers, designed to keep out the worst dirt and wet, had failed), so it’s a good idea to get it professionally looked at.
Gravity. And it’s not just your car that it’s holding down.
And here I was thinking it was The Man holding his car down.
It seems to have an invisible touch yeah?
It takes control and slowly tears you apart?
Could definitely be a seized disc brake. The brake discs tend to rapidly rust when they get wet. But seems like it would just be surface rust and not be binding the pad to the disc.
But start with the simple stuff, is your parking brake on?
Its almost certainly your parking-brake*, I had this happen to my car after parking it overnight in my garage. Like you I was utterly confused and I had to get my brother to come and tell me what was wrong.
So good news is its almost certainly not a serious problem. 
*which we call the ‘hand-brake’ over here.
I see that you are in Medford Oregon, land of eternal rain. Thus, rust is not the issue since it does not do this every day. It is not the water from the pressure washer forming ice between the brake shoes & the disc. It is not yet cold enough there at night.
It is probably the hand brake. Drive it as is & if it does not happen again, it was the water/soap mixture that glued your brakes on. If it happens again without the pressure washing, then I would suggest, in your case, that you get it looked at my your local neighborhood garage. Pressure washing can force the soap/water spray into the brakes past almost any dust cover or seal no matter the condition of the part.
Be careful when you use the pressure washer. I find driving the car for at least 30 minutes after pressure washing gets things warm enough to evaporate that liquid out of places it does not belong. Living in the high country where ice forming on things can cause issues, I have found that doing this driving saves me some hassles. Besides, I like to drive.

Dumb question from someone who doesn’t have a newer car: people can easily drive with the parking brake engaged and not notice it. It won’t stop your car completely whereas the foot brake will., is my experience atypical or have things changed?
Have you kept current on your Gravity payments?
I could drive my 1998 Civic around with the e-brake engaged. Same with my current car, 2015 Impreza. It feels different, obviously, but it can be driven.
Remember, Gravity isn’t just a suggestion: it’s the Law.
You know how this old world can start getting you down?
It does that for cars, too.
It’s the only way to live.
