Holden Colorado 7 / Trailblazer Questions & Answers

I just purchased a new trailblazer and have just installed a tow bar and harness with ecu. The problem is that the tail light and brake light are on the one red wire at the plug and when I test the vehicle lights the brake and tail are on one wire. How do you get the tail light and stop light to seperate as the tail light is supposed to be brown and stop red?

My 2016 Colorado 7 lt air-con is not working properly. Have check the fuse and it seems okay.

Would really like a solution as I have young children and summer is so hot to drive around with in the car.

My husband & I purchased a second hand 2017 Trailblazer (Z71) 8 months ago with the specific intention to tow our 18 ft 7 caravan. We have travelled we had travelled around 30k before we started having an issue with the car going into “limp mode” after we’ve been driving for some hours & towing.. this seems to be an “intermittent” issue. We have had our car looked over by 2 Holden service centres & also took the car back to where we purchased it.. no one seems to be able to work out what the problem is! Our car has only come up with an error message a couple of times which indicated the “Trailer interface module” but still no answers.. this problem started under warranty, should we be pushing for the “Trailer interface module” to be replaced by Holden? We would also like to know if anyone else has had a similar problem? Thank you, Narelle

Hi, few questions please. I have a 2017 Trailblazer LTZ. My questions are:

1- why do the indicators double flash when I’m locking the car, even when I’ve not had any windows or other doors open?

2- why does the radio display sometimes show the song title and artist and other times doesn’t?

3- why does the radio display stick/jam on a particular setting when it’s recently been really cold temperatures? E.g. I have local radio station name but where it says either radio station description or the artist/band info, it’s showing the song that played last week when the temperature was really cold.

Any ideas gratefully received.

Does the 2018/19 Holden Trailblazer have automatic boot - ie is there a button on the key chain or can you wave your foot under it for auto open or is it at least a soft touch button? Or do you need to physically lift it up to open ...

Hi all I’m very new at this and have just purchased a 2022 LTZ and and wanting to know what leather cleaner and conditioner you use. Thanks

I have a persistent rattling noise coming from the tailgate. I seem to think it may be the plastic moulding around the window, but everytime I put spaces in it seems to continue rattling somewhere else. Does anybody else have this problem?

I have a 2018 trailblazer & I'm at the drive-inn, how do I turn the tailgate lights off to lay in the back ?

I have a 2017 trailblazer. After 40,000 km the engine management light came on and I took it to a Holden dealer. They diagnosed a dirty valve in the inlet manifold and removed the manifold to soak the valve in a solvent. This fixed the problem but after only another 5000km the light is back on.
Has anybody experienced a similar problem and is their a permanent fix?
