Psycho Posted April 15, 2008 Report Share Posted April 15, 2008 Hi yesterday I found a funny rubber part under the middle of my 99 STS. I checked the shop manual, but I couldn't find it in there. Has anyone an idea??? Thanks.... Psycho LPG Link to comment Share on other sites More sharing options...
JimD Posted April 15, 2008 Report Share Posted April 15, 2008 That would be the fitting that allows water (condensation) to drain from the A/C evaporator housing. Jim Drive your car. Use your cell phone. CHOOSE ONE ! Link to comment Share on other sites More sharing options...

Thank you very much JimD! I will check this tomorrow. And I found it in the shop manual volume 1 HVAC System page 1-73 Defroster nozzle... best regards... psycho LPG Link to comment Share on other sites More sharing options...
JohnnyG Posted April 16, 2008 Report Share Posted April 16, 2008 Defroster nozzel? That doesn't make sense. Defrosters are up on the windshield, not under the car! JimD is more correct on this. And by the way, make sure it is clean and open when you check it, it can be a source for problems such as musty odor, backed up water into the cabin, and poor A/C performance if it gets plugged. Never underestimate the amount of a persons greed. Link to comment Share on other sites More sharing options...
KHE Posted April 16, 2008 Report Share Posted April 16, 2008 Be sure to re-install the piece on the evaporator housing. If you do not, the evaporator will not drain due to air being forced into the evap. housing and the condensate will overflow into the passenger compartment and make quite a mess...

JohnnyG Posted April 17, 2008 Report Share Posted April 17, 2008 Defroster nozzle is what the shop manual calls it. I know. I'm just sayin' that I have no idea how this was lost in translation. I'd call it a condensate drain, as JimD did. If you don't believe me, just plug it off and see what happens! Never underestimate the amount of a persons greed.

I have an original Cadillac USA shop manual, no haynes or cheap copy. Psycho LPG Link to comment Share on other sites More sharing options...
JohnnyG Posted April 18, 2008 Report Share Posted April 18, 2008 The translation from the language of the people that write shop manuals, to the people that actually use them. The differences can be quite striking at times. Never underestimate the amount of a persons greed. Link to comment Share on other sites More sharing options...

BodybyFisher Posted July 8, 2008 Report Share Posted July 8, 2008 It is referred to as the evaporator drain, not the defroster module. The defroster module is located inside the car and is the two defroster vents, the manual is confusing. I can only imagine that the evaporator drain is part of the evaporator housing, you will need to access it from under the car on the passenger side. Here is the procedure that includes the evaporator drain HVAC Module Assembly Replacement Removal Procedure Tools Required J 39500-B A/C Refrigerant Recovery, Recycling and Recharging System Recover the refrigerant from the system.
