Remote Vehicle Start works according to the manual. I entered the vehicle and inserted the key and turned it once to run but did not turn on heat, no display lights and could not put in reverse. Had to turn off the car and restart normally. The Climate controls were both in AUTO at the time. It was cold, about 45. What am I doing wrong?

    No. I am sure it is factory installed. We bought the car used in June and it came with the car. Will probably take it back to the dealership and see what they can do.

SOURCE: Only cold air on passenger side

I would first check and make sure that you have enough Freon in the system, on climate control dual systems only one side will put out cold air if the system is low on Freon. Eventually, both sides will put out warm/hot air if the system continues to loose Freon. As with all leaks the system should be checked and then the leak causing component replaced/repaired.

SOURCE: 98 buick century , with auto climate control ,

is it HOT or just not as cold. If its HOT, like heated air, there is a door problem, if its just not cool, the a/c refridgerent is low and will need a recharge, most likely the comp is leaking.

SOURCE: GM '97 Buick Le Sabre Climate Control flashing display

I did the exact thing with my '98 buick LeSabere. I am certain that the dealer would have to look at the components and relays and fuses. I had problems with Precision tune mechanics telling me there is nothing wrong with the electrical system, even though I still get a Flashing temp gauge and do not get FULL heat even when it's blasted to 90ºf . [Precision Tune got heat on the windshield and floor.] Moreover, the car is possessed with glitches; I am not getting heat on the windshield and the floor is not hot enough to warm the cabin.

Howdy,
If your AC system is low on Freon, the system goes into a no run mode. If you disconnect your battery for a few minuets the computer resets itself. Then the Freon level can be checked by a friendly shop. Might find it low. Good Luck!!!!!!!!!!!!!!

Why did the passenger side of the dual climate control on my Buick Lucerne only start blowing cold air? Have no heat on that side, just air conditioning works.


May b a blend door issue..
If its electronic unit then maybe a actuator gone bad
If controlled by vacuum then a broken/loose hose
Does that side change from different settings(dash/floor/defrost even)= blend door issue usually
