I have a 2007 chery trailblazer i recently got a recall letter on my headlights and air conditioning but lost the letter and i need to speak someone about this.

their are many problems with any vehicle and envoy/trailblazer[top seller ] have troubles some of the complaints were in the early 02 -03 the sun gear in transmission would crack some were the rear light panel corrosion problem a recall for some 06-07 in the northeastern area for drivers door circuit shorts due to cold weather road salts being able to seep past window and a few not many of the 02 trailblazers /envoys for an air bag module inspection last year recall for some 06-09 for a drivers headlight module the 05 had some for windshield sealant not fully cured their has not really been major problems with them but like with any vehicle the owner will either love them or hate them

I would check to make sure they are not burnt out, Then check my fuses, then check my switch.. It is a matter of elimination

you will need to remove the front grill face plate that goes from the front of right headlight to the front of the left headlight. then you will need to remove the bolts at the top of the headlight housing. then you need to pull outwards on the assembly to access the headlight bulbs.

my suggestion is that you check/ replacr the HDM(headlight driver module) relay in the main fuse box located under the hood near the battery.

I would suspect the clutch on the air conditioning unit, also if the unit is overcharged
from a recent charge this would also bog the engine. At speed it would not be as pronounced.
Hope this helps.

I read over the recalls and they do have recalls on brake and turn signal lights but not the low beam headlights while driving at night.

Sounds like the relay or headlamp driver module relay 46, for the headlights is going bad, though.
Or, it could alternatively be bad grounding of wire somewhere or bad wiring in general.

I would check in the underhood fuse box for the relay and see if wiggling it to ensure a good connection helps matters.

It sounds like you have a blend door issue. You need to get in your dash to fix this.
