Question about 2004 GMC Envoy

1 Answer

I have a 2004 GMC Envoy. I have a leak to the passenger side floor board when its hot and the air conditioner is running. It is not antifreeze, so I take it that a weep hole for the condensate is plugged up. How to I clear this problem?

Damn spiders,Find the hose from under the vehicle and blow some air into the hose,not to high pressure,watch out for the water as it usualy comes out afterwards.Then turn on the blower on high and you should feel some air coming out of the hose.You might want to try the blower on first to see if it actually blocked and not some other problem.Please rate this if it was helpful Thanks

Wet passenger floor board/2004 Envoy


The moisture drain for the air conditioner is there. When it plugs up, excessive humidity removed by the A/C will leak out onto the floor board.

Air conditioner leaks on floor


Sounds like the outside drain is stopped up.
There should be a tube coming out of the firewall near the passenger floor.

On my 2004 Gmc Envoy, Heat only comes out on passenger side, still blows cold air on drivers side. Defrost, floor and vents all produce air flow. Rear heater works fine. A/C works fine. Any idea?


Sounds like the driver's side temperature actuator or blend door are defective. Part of the dash needs to be removed to access these parts.

No cold air w/air conditioner on for a 2004 GMC Envoy.


Can't go by the pressure. Ck the large lone coming out of firewall, should be col. Small line at ac condensor in front of radiator should be hot.

Static pressure on high side probably 80psI Running 30 on the low side and 1130. will vary depending on oiutside temp Hope this hekoped

2004 Envoy Smell like Anti-freeze when turn on the air


probably is a small seep in the heater core. does not have to be leaking enough to find any inside the car to have a strong smell in there just a small seep that makes the heater core wet will do it.

Height are not balance


their could be a tier that is low. Their could be more weight in the passenger side than the drivers side. check the pressure in the all the tiers and please let me know your findings.

Leak to the passenger side floor board.


there idef. a drain for the water and is located below heater box on pass. side under vehicle. usually rubbertype hose with sort of closed off end maybe 2" long. (sometimes they are hidden, look carefully) i use shop comp. air to clear but a straight piece of wre may be just as good. also consider replacing cabin air filter behind glove box. probably restricted as well
