I washed engine at car wash ,now motor will not rev and runs bad

front pump/washer?not head lamp washer.
3 causes
electric fail path
pump bad
pump hoses and nozzles clogged.
Scan the OBD2 port and see BCM waster errors.
I see lots of Bnnnn errors. there.
what I do after scans
is measure pump voltage at pump pins washing.
cutting the job in half ,just 1 test.

PDC fuse 184 dead killls it all. wiper and wash both
the BCM is told to wash digitally and the BCM has drivers on its output to the pump motor and NO FUSES>
the fuses are not there ,but are ELECTRONIC regulators.
if motor is dead, the wiper switch is bad.(wash pins)
the car has wiper wash tank empty sensor that if tripped
may cut washing dead. as we know running any pump dry
wreck a pump. so

no fuse no relay for wash period
yes wipers but not one word that the do work.

You obviously got water in an electrical connector. Disconnect each one and blow it out with compressed air. This is why you should NEVER power wash an engine.

some part of the igintion system is get wet does it start after a while when it drys out

Bad transmission if engine runs fine and revs well in park or neutral or bad motor mounts

you can take it to the car wash. making sure the vehicle is warmed up before washing. when you go to wash the motor make sure all the caps are in place. oil/power steering etc. i like to have to motor running while i clean it . it keeps the water vaporizing as i wash it. soap it down and rinse it off. after driving it home let it run for about 15 to 30 minutes with the hood open to help vaporize the rest of the water so it doesnt become a problem later. hope this helps

emission controls are sensitive and washing engines can sometimes aggravate things.

A dirty engine isn't necessarily a bad running engine. But, when you pressure wash or even hose it down, gremlins can appear as water enters cracks and crevices in the wiring and accumulates in plenums in the engine compartment.

I would have the engine codes pulled on the OBD-II system to see what is awry, and diagnose the system from there.

Good luck to you.

take back to carwash and hit reverse button. it will remove all the water out of engine---bad for electronics, that why your auto no work good anymore never wash engine at car wash, bad bad bad. water goes where it shud not go---more bad,

that why car wash have reverse button. to reverse water flow out of car engine. BAd bad bad

may have bad gas pedal sensor, or throtle body motor, thats only if you step on gas pedal and engine wont even rev up, if it rev then possible trany problems.

disconnect battery & dry out all the electrical connections!!!!

Don't "wash" the motor, like you wash the outside. Did you pressure wash it? God people are too freakin anal retentive and go screwing up their engines. Next time use engine cleaner and try not wet any wiring harnesses or anything electrical. You probably killed a sensor connection or something.
