Ambient temperature stuck on minus 36 and AC will not blow cold air
Motor Runs Good . But the transmission doesn't. It starts in 2nd gear then shifts into 3rd at 30 MPH. it will not shift into 4th or OD. Reverse work fine. A few days before this started ,I noticed that holding the throttle steady between 40 and 60 MPH It would feel like the Tork Converter Lock-up was kicking in and out. Engine RPM's would rise and fall 200 RPM's .I also noticed that I could simulate this same issue by slightly depressing and releasing the throttle. I don't hear any funny noises or notice any strange sensations except sluggish starting in 2nd gear. I have 3500 Mi. on re-man. transmission , fluid is nice ,clean and red . does not smell burned.
I have no dash lites/tail lites. My fuse in dash fuse box is not hot. I preplaced it with new fuse and it's still not hot. Is there another fuse somewhere else

Hello I drive a 2004 GMC Envoy XUV, has a 4.2-liter, 275-hp 6-cylinder engine and is RWD. I'm wondering how often I should be changing the oil. I have a long highway commute so I drive at least 166mi total per day. Right now has 88.5k miles on it. I've been going with full synthetic in hope to go longer between oil changes, how often would you all advise taking it in for a change?

When bought....Capital GMC in Regina Dealership said they would get extra keys for my 2014 GMC Terrain. Never rec'd them yet. They brushed me off and I pd cash for 2 of my vehicles there. Going to Ford next time!
Yesterday my 2000 jimmy wouldn't start security light was flashing. Now I reset that by opening driver door and locking them and shutting it. Now it turns over but won't start. Fuel is going through. Just have no clue what's going on. I know the o2 sensor is bad. Could that be it?
My 2013 gmc terrains liftgate it closed and won’t open. I’ve tried using the dob but nothing. I’ve tried manually nothing. The only way I can get it to open is by going inside and popping that inch wide circle cutout out and pushing the lock open. I’ve tried checking all the fuses associated with the liftgate and they’re all good. I’ve also tried setting the automatic liftgate setting to off and manually trying to open it but nothing. Any help would be greatly appreciated. Thank you for your time. Sincerely frustrated 2013 GMC terrain owner

The fuse changed the relay changed and top it off security light blinking.
