#23 of 49 98 GMC Sonoma A/C condensation drain hose by brivers63 Aug 28, 2007 (1:34 pm)
I searched and searched and could not find an answer to this.   Where is the a/c condensation drain hose on a 1998 GMC extended cab Sonoma? I am getting water in the cab on the passenger side, coming down from the firewall when the a/c is running and after it is shut off. I have looked under the truck as best as I can and cannot find the drain hose. Any help to put me in the general area would be appreciated. Replies to this message: gonogo (Aug 29, 2007 9:52 am)

Replying to: mike182 (Feb 09, 2007 2:41 pm) WARNING This Applies to all owners looking at coolant level.   Stop looking in Coolant over flow tank for confirmed level of engine coolant. You'll get faked out every time.   You need to only look in radiator.   First sign of no heat is low coolant. Second is plugged heater core. Be careful and gentle when flushing out core to not over do it with outside pressure source.   You could force a weak heater core to leak all inside vehicle.   If you applied radiator stop leak in the past, then take a minor guess where all that crap is now.   If you have to use these products, then take out the heater core from the process by removing the heater hoses from the engine.

Engine will not heat up over 150 degrees. I changed the thermastat and blocked the radiater but still will not heat up.Could it be a blocked heater core?

Replying to: snowx132 (Feb 09, 2008 11:56 am) You'll need a 1/4 in drive set, Phillips and flat screwdriver, drop-light, and patients. Last time I removed and replaced the dash on my 97 I only had three screws left over. That's a personal best for me. Good luck

Replying to: snowx132 (Feb 09, 2008 11:56 am) When I did my 2000 Blazer, I followed the Haynes manual. It wasn't perfect, but it had 90% of what I had to do. The dash, while somewhat intimidating, wasn't that bad. For me there was a piece under the dash that had to come out in order to get the heater core out. It took me hours to finally find the 2 studs that were poking through the firewall. I had to remove the right front tire and go in through the wheel well to get to them. If I had had good direction this would have been minor, but as I said, I lost hours just trying to locate these on the engine side of the firewall.   Good luck

#32 of 49 2000 s/10 cool/heat control by danpstew Mar 18, 2008 (6:38 pm)
when the control is to cool, there is warm air coming out of the floor vent, if the a/c is on max its cool coming out of the dash, not cold. whats to be checked? please advise. Replies to this message: gonogo (Mar 19, 2008 8:41 am) danpstew (Mar 19, 2008 6:24 pm) gonogo (Mar 20, 2008 8:50 am)
