2002 GMC Sierra 1500 P/U w/4.3 lt. V-6, I have had to have the A/C condensation line covered three times with the foam insulation from my dealer. They also have to clean the corrosion from the distributor, remove the screen in the bottom of the distributor, clean the spark plugs and replace the cap and rotor on each occasion. My truck is currently in the shop again to have the distributor replaced. This is at a cost of around $680 to replace the distributor, new plugs due to fouling and wires. I have spoken with General Motors and to the dealer several times regarding the temporary fix (band-aid). The air condition condensation line is located directly above the distributor and they refuse to move it. It has become increasingly apparent their repair is not a fix but a temporary solution to get you out of warranty. There has been a recall sent to me but does not show in your listings for the subject vehicle. This problem is very dangerous, your vehicle usually gives no signs before leaving you stranded in the middle of the highway. My question is why the dealer gets away with a temporary fix and not a resolution to the problem ? I believe the air condition condenser line should be relocated away from the distributor altogether. GMC is well aware of this problem and rectified the re-engineering of the A/C line route in the 2003 models.
