'98 GMC Sierra is leaking water inside the cab on the passenger side when I have the A.C. turned on. I can see where the water is coming from, but I can't get it to stop leaking.

There is a drain under the vehicle under where the ac lines go into the vehicle cab',look directly below the ac lines,it is hard to find but it is there ,use compressed air ,like a air compressor or air tank,with a blow gun and blow the drain out,if it unclogs the drain,it will pour out like a water fall,if this was at all helpful,please rate thank you.

I have a cold air leak on the passenger side of my 2004 GMC Sierra 1500. Where is the air coming from and how do I stop it?


Some of these pickups would develop an air leak between the air inlet section of the HVAC box and the cowl or firewall area. This leak would allow cold air to seep into the cab [usually by the passengers feet] in the winter and hot air in the summer. The other rarer cause I've seen is the recirculation door actuator motor sometimes won't hold the recirculation door closed which can also cause a leak. Sorry but I don't have a procedure to fix either of these for you as the ones I saw were still under warranty and went back to the dealers. Hope this helps narrow it down and good luck!

4 wheel drive gmc sierra 1500 1993. the cigarette lighter, radio and inside cab light suddenly don't work. is there a relay or fuse in engine compartment i could look at?


your fuse panel is either under the dash by the drivers left knee or on the side of the dash where it meets the door. the radio fuse should be the second from the top right side of the fuse panel. its a 10 amp fuse. the power for the switch should be a 16 gauge wire run from the passenger firewall (under hood.) behind a plastic cover where a lot of wires are bolted to posts. that red wire feeds power to almost everything in the cab. it runs behind the glove box and has a disconnect there. if the fuse is not bad and the wire looks good, check the ground on the passenger door "open switch" (the one that is supposed to turn on the dome light. that is where the whole system is grounded for the int. lights lights

the small radiator just inside the cab, where the hoses go to the heater is leaking. You may try using stop leak (many don't recommend this) or take off the heater radiator. it will probably get worse when you turn on the heater and fog up the windshield if not fixed. hope this helps.

No power to passenger door.


Check the 10 amp pdm fuse in the cabin fuse panel.
