I believe cabin filters were done away with in 03 but maybey not in the Suburbans. The evaporator probably is moldy. There are commerially available products to sanitize the everything but I've heard mixed reviews. Does it drain condensation on the pavement when idleing?

Sometime this will work:

 

turn AC on full.

 

Spray lysol into intake at base of windshield.

 

You should always try to turn off your AC and let the fan run on high about a half to 1/4 miles from your house. That way it will dry out the system and not let the moisture sit.

My 04 burbs AC started smelling like vineger. Any idea's how to get rid of AC smells ?

There is a product made by BG called Frigi fresh that works great. You spray it in the cowl as the air's running and it kills the smelly bacteria. I use it and have no complaints at all.

Might not want to sit in the car while doing this. Lysol isn't exactly lung friendly LOL.

I've got some product from BG called Frigi-clean

It is a foam type of cleaner that you inject into the evap box.

 

I used to to that as a mobile service. You drill a 1/4 inch hole just in the plastic on the blower side of the evap core. I used a step bit as to not go in more than 1 inch.

 

The kit comes with a brass fitting you thread in.

Then you hook the fitting to the poly hose on the can and empty the foam into the evap box then you turn the fan on high for about 1 min. Let it set for about 15 minutes and the foam loosens all of the dust, debris, algae, bacteria, and disinfects. Does a great job. Then I shot in another BG product called Frigi- Fresh which is kind of like Lysol, bug smells way better and also disinfects and deodorizes.

 

If you AC is not very old and you've never smoked in it, you might just get a can of Frigi-fresh and try it.

 

What alot of people don't understand is that when you pull up somewhere and shut the engine off with the AC running, the evap core is like a ice block and then you kill the engine and the fan stops and you leave your car. The ice melts and the evap core stays moist and then your car's interior gets warm.

 

Moist and warm.. bacteria, algae..etc..

 

if you wanted to avoid this, you should run your fan for a minute without the ac on to dry the coils out before shutting the car off, but who wants to do that?

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
