When I turn the air conditioning on in my 2013 GMC Terrain there is the smell of mold. Apparently the air conditioner doesn't get rid of any moisture left after using it.


There is a procedure for this condition. GM says to flush the core with a cleaning agent they sale. I have found Lysol Fresh scent does a much better job of curing the condition.Spray the Lysol in the outside air intake vent while the vehicle is running with it set to max a/c and fan speed also on max. It will take about 1/4th can to fully clear the mildew smell and stop it from growth. When parking the vehicle always put it in max a/c position so the fresh air outside the vehicle will dry out the coil.

Reason why I cannot get Cool Air into cab? Hot air only which is a problem on a long journey in summer temps.


Most good shops that service air conditioning for vehicles have a little thermometer that can be inserted into the dashboard vents of a vehicle to measure the temperature of the air coming out of the vent. This will tell you if the air conditioning needs to be serviced or repaired.
I do not use one of those thermometers, but if I remember correctly, they should show around 40 degrees when the AC is working right.
Start by having this checked.
God bless your efforts.

My 2008 chrysler will not start without a hard jump and there is a rotten egg smell coming from engine


1. I answered the starting and battery question in your duplicate posting on this question.

2. The air conditioning system requires a drain system to direct condensation (ie water) out of the vehicle. It is quite normal for the air con system to produce water as you know.. If you have water leaking into the car interior when running the aircon it is an indication that the drain is blocked and the water cannot escape. The drain tube runs to the underside of the vehicle and if it is blocked this can often be right at the end of the drain tube under the car. That is the first point to check.

While either of the solutions may be correct (unless someone lives in Florida or somewhere their using A/C in January, unlike Wendel), the main problem most likely causing the wet carpet is a clogged evap/heater box drain. You can usually crawl under the vehicle and locate the drain on the passenger side lower firewall. It is usually a rubber elbow that points downward and gets clogged with debris and slime over time. If it's a heater core you can feel the anti-freeze between your thumb and two fingers (it feels like a light oil and then sticky as stated earlier, but should now be on your driveway). If it's water and your using A/C everything should be normal. If it's water and winter, you have bad seals or debris holding open your vent inlets just under the windshield (this might show up better by noticing difficulty getting the vehicle to warm or defrost windshields in fair amount of time and even the smell of other vehicle's exhust fumes when you have the system set to recirculate air). This is not usually an exciting repair.

What does code 446 mean on the 1996 Chevy Blazer?


P0446 = Evaporative Emission Control / System Vent Control Circuit Malfunction.

Check it, and before you replace the Evap Canister read this:

Subject: DTC P0446 (Restricted/Blocked EVAP Vent Path) Set, Service Engine Soon (SES) Lamp Illuminated (Replace Hose/Evaporative Emission (EVAP) Canister Vent Asm) #02-06-04-037A - (02/02/2005)
Models: 1999-2003 Chevrolet Silverado Models
1999-2003 GMC Sierra Models
--------------------------------------------------------------------------------
This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 02-06-04-037 (Section 06 -- Engine/Propulsion System).
--------------------------------------------------------------------------------
Condition
Some customers whose vehicles are operated in dusty type environments, such as farming or mining off-road type applications, may comment about the illumination of the instrument panel SES light, with a DTC of P0446 (Restricted/Blocked EVAP Vent Path) being set.

Cause
Dirt and dust intrusion into the EVAP canister vent hose assembly, resulting in restricted air flow, may cause this condition.

Correction
After following the Service Manual diagnostic P0446 and determining that the EVAP canister vent valve is the cause of the SES light, replace the existing EVAP canister vent hose assembly with a new assembly, P/N 15086429. This new assembly has an enhanced filtering capability and a filter element that can be easily removed and cleaned. To ensure correct installation, follow the procedure below.

Raise the vehicle. Suitably support the vehicle.
Disconnect the EVAP canister vent valve electrical connector.
Disconnect the vent valve pipe at the EVAP canister.
Remove and retain the EVAP canister vent valve bracket mounting bolt.
Disengage, from the underbody, the two vent valve pipe clips securing the pipe to the underbody.
Remove and discard the complete EVAP canister vent hose assembly.
Position and secure the new assembly to the underbody using the existing hole and mounting bolt.
Tighten
Tighten the bracket mounting bolt to 12 N·m (106 lb in).

Install the two vent valve pipe clips into the existing underbody holes.
Connect the vent valve pipe to the EVAP canister.
Connect the EVAP canister vent valve electrical connector.
Lower the vehicle.
When properly installed, the new EVAP canister vent hose assembly will be positioned outboard of the original installation location. This new location provides clearance for accessing the filter element for cleaning purposes. To access the filter element, disengage the filter cover to valve locking finger by gently lifting the finger upward while simultaneously rotating the filter body clockwise. After approximately 45 degrees of rotation, the filter can be disengaged from the valve by gently pulling outward. The filter cover can then be removed and the filter element and body can be washed with soap and water. Prior to reinstalling, ensure that the body and filter element are dry.

When I turn on the AC a moggy smell blows out of the vents. However, if I turn the AC off but leave the fan blowing air through the vents the smell go away a little. What could be causing this problem?...


mould in evaporator case?
some vehicles have a pollen filter(air conditioning air intake filter)not sure if your vehicle has but check if it has, may need replacing.
check plenum chamber(area under front windscreen)for leaves and debris.
then can try and spray mould killing pressure can(glen 20)air freshner in through intake air places under front windscreen with windows down air cond on full fan speed on fresh air while engine running or not depending on how long and how bad smell is.
may also pay to check for blocked air cond. drain tube, is it dripping water when running?
service centres or hire places have also got fragrance and mould killing machines you can use inside vehicle under similar conditions as above(ozoneator)

Air conditioning


sounds like the linkage in the dash controls are backwards or mislabeled relay was put in vehicle which has opposite properties of which your describeing
locate the control relay and or linkage check this first then replace the control relay cause during the cold months the relay freezes open or shut and then when moisture disapates is creates rust in the relay which gives it a bad point making things reverse
