In the last few days, every time I run my A/C on my 1990 XJ, it dumps water on the passenger floorboard - especially when I turn left or accelerate.

I would assume that it is condensation that builds up under the passenger dash somewhere and dumps out when I turn or accelerate - but it is a lot of water and soaks the carpet.

Is there a drainage hose or something that may be clogged or become disconnected? I looked under the dash but didn't see anything.

Any suggestions?

 

on the firewall just below the fan there is a drain. passenger side more to the center than the fan. suck or blow it out

 

On the engine side or passenger compartment side?

The drain goes through the firewall on the passenger side at about frame level.

 

Hit it with some compressed air. Here in florida dirt doblers love to build nest in um.

 

Found it! It was the drainage hose. It has a little rubber tip on the end that is kinda pinched to keep stuff out. It was stuck together and when I unstuck it, a whole bunch of water poured out. Now, no more dripping in the cabin.
