In most cars it's okay to get the carpet pretty wet for cleaning, but you need to suck it dry with a wet/dry vac or proper carpet extractor and b)immediately dry it out as much as possible, like leaving it in hot sun with the windows and sunroof all cracked a bit and a fan or two circulating air around. Letting the car get pretty hot and then driving it around for a bunch with the A/C on will help, too. Car AC systems are very powerful. However, some car companies put control modules in the passenger footwell (like engine control modules, sometimes ABS or airbag controllers), so it's worth looking at a parts diagram or googling around first.
