Question about 2002 Chevrolet TrailBlazer

1 Answer

Does a 2002 chevy trailblazer have any type of filter in a/c unit

I took my vehicle to a mechanic to get the a/c working, he replaced a high pressure seal which they did fix, but the a/c only worked good for a week. Then I took the vehicle back to him because all the freon leaked out. He then told me that the problem was that the A/C filter was clogged up and no circulation was going through. Is there such a thing as having a filter for the A/C system? 2002 Chevy Trailblazer is the vehicle.

2004 Chevy Trailblazer transmission shifts but at High RPM's


have a pressure test done on the transmission to check for internal problems. run fault codes to check for TCM and other related faults. Have a band and clutch pack adjustment done . If it all checks out but the problem persists then you may have to consider a removal and overhaul option.

2004 Chevy Trailblazer misfire with codes P0300 and P0410


DO NOT go back to this ripoff artist, he either doesn't know what he doing or is taking you for a ride.
Misfires are usually caused by bad spark plugs or coil packs. Find another mechanic.

2002 Chevy trailblazer recharge ac


Go to the passenger side of the car and you will see some colored caps coming from the condinser. It looks like an aluminum cylinder. Follow the the lines and you will see something that looks like big valve stem caps that you remove to put air in your tires. You will find it there. The colors will be either green or black. You will not be able to hook the servicing hose to the high side so do not worry. There is only two caps on the vehicle that looks like that.

Replace shift linkage bushing on 2002 trailblazer


All that was wrong with my 2002 Trailblazer was a 6.00 part my husband bought at PepBoys! It's the plastic grommet/bushing that broke that holds the shifter cable to the linkage...took him 10 min to fix!

Service four wheel drive light on,cant shift into 4wd cold only ,below 45F,drive awahile resatrt the truck it works fine,warm days no problems .


Vehicles: 2002 Chevrolet Trailblazer 4WD 4.2L SFI DOHC 6-cylinder

Your front 4WD Transfer case is low on Gear Oil.
On warm days, the Gear Oil expands slightly, and is less viscous, so the "Service 4WD" light stays off. On colder days/mornings the story changes.

The following paragraph has info applying to the manual differential only:
The 2002 Trailblazer (the first year Chevy made the Trailblazer) has a Front Differential using 1.11 (that's 1 and 1/9th) Quarts Gear Oil, and a Rear Differential with a capacity of 2.29 (thats 2 and 2/7ths) Quarts Gear Oil.
The Gear Oil needed is GM Part No.12345349 or GM Part No.1052931 (they're identical), also known as "GM Synchromesh"(R), which is a type of GLS (Gear Lubricant, Special), also known as "Manual Synchromesh Transmission Fluid 5W30". A synthetic version of which sells for $12.70/qt (USD) at
http://www.amsoil.com/storefront/mtf.aspx

This is not to be confused with 5W30 motor oil (which can be had for $3.00/qt (USD)).

The 2002 Trailblazer 4WD Transfer Case (NV126 Transfer Case) capacity is 0.8 Liters of GM Part No.12378508 (US), also known as "GM Auto Trak II"(R).
Note that one Quart (US) = 0.946 Liter, so 0.8 Liter = 27.06 ounces.

Red Line sells something that they say replaces both GM Synchromesh and GM Auto-Trak II for $12.14/Qt and $44.55/Gal (US) at
http://www.shopwiki.com/Red-Line-MTL-70W80-GL~4-Gear-Oil-%281-Quart%29

13 Manufacturer Recalls apply to the 2002 Chevrolet Trailblazer (model year 2002 was the first year Chevy offered the Trailblazer), and two recalls pertain to the 4WD Transfer Case. Note that one of the recalls applies to only 895 units, so your vehicle is unlikely to be affected by this Transfer Case recall.

Model Affected TRAILBLAZER

Recall Summary
VEHICLE DESCRIPTION: SPORT UTILITY VEHICLES (4 WHEEL-DRIVE). SOME OF THESE VEHICLES WERE BUILT WITH A RANGE SHIFT COLLAR IN THE TRANSMISSION TRANSFER CASE THAT CONTAINS CRACKS.

In my 02' Trailblazer oil pressure gauge goes below 0


I have this same problem with my 2002 trailblazer; however, I goofed up and had a mechanic look at it, since I was perplexed as to what was going on with it. He told me the oil pump needed replacing and it ended up costing me around a $950. Needless to say, it still happens. A grand down the drain - it wasn't the oil pump. The oil level is always good. This generally occurs when I've run the vehicle for a while and then come to a stop. It occurs quite often during the spring/summer and doesn't happen all that much during colder months.
