The very first thing you need to do is to check for fuses or
say faulty fuse. Secondly check fan which starts along with air conditioner, it
might be manually switched off or the fan may have been clogged. Also reason
can be lack of refrigerant - charge your air conditioner with refrigerant. Last
thing you need to check is cooling coil - the cooling coil may freeze if there
is no refrigerant in the system.
On the underside of the bblower housing is a drain. The blower housing is on the firewall in front of the passenger in engine compartmentA big black box. Feel around underneath it and when located, squeeze like a coin ourse and finger the scum out of it. and the water should drain.The fan is another issue. Either no power to it or its defective. chk f4 blown fuses or touchy switch.
Three possibilities; All related to blown fuses, 1- Fuse blown in the engine compartment LH. 2- Fuse blown in the cabin forward LH below the dashboard (below your legs left hand). 3- Fuse blown in the harness (wire bundles) below the dashboard very easy to reach with your hands “just look underneath steering wheel ". U said " The air conditioner blows, but the air is not cold. " Yes only the fan working which might receiving power independent all from those other mentioned things. If all fuses OK. Then look for broken wires. Regards; MAR
Possible solution for susuns: turns out my problem was an improper freon charge. If your problem is the same as mine your a/c cools very well, but stops blowing air after about 20 minutes. If so, your evaporator core is freezing over and the ice is blocking air flow. Also after parking the truck water will continue to drip from the truck for a long time. To test this theory next time it occurs, switch the selector to vent and the fan to high. You should notice the air flow return within 5-10 minutes or less, however the air will still be quite cold due to the ice formed on the core. If all this fits your situation, take your truck to an experienced technician and have the freon pressures checked. My system needed to be charged a little on the high side to prevent the freezing up.
Hope this helps, capn0623
possible low charge,possible leak,auxillary fans possibly not coming on,check you see when you turn your a/c on,do the fans get really loud occasionally,all the time,or not at all,if not at all ,you have a problem with the aux fans not coming on-
