Is it just me or did GM not put a low pressure port on the A/C. I need to check and top up my a/c for summer.

Then again, the laws of physics only apply within a band of parameters. I would suggest one think of trying to do hot laps at -35 below zero, now sucking in all that cold air with the equivalent windchill and at high rpm's. Then that cold dense charge hits both the in coming fuel from the...

For that limited towing need you would be OK with 3:73 or even 3:55, as long as you are not a lead footed character. Acceleration will be a little lower, I guess whatever you get the best deal on.

My wife's BMW X5 has summer 315-35-20 on back & 285-40-20 on front. She "likes" the look. The truck handles like it is on rails BUT-it will shake your teeth out-it rides like a buck board. Her winters are 265-55-18 and they are so smooth and still handle as well as you'd want to lean a 6,000lb...

Seems to me it depends what you are towing and where you are towing. Heavy 10,000lbs plus loads through mountains-stay with 4:10, 5,000lbs on the flat-you could get away with 3:73. Check your RPM & gear at the highway speed you tow at for your load. If you are in the sweet spot it won't get any...

Problem solved- I finally took it to GM Dealer as nothing was making sense. They diagnosed a shorted out underhood fuse box, also highly recommended I change the location of the trailer power wire off of the connection of battery to fuse box. Got it home and removed the whole fuse box and...

I dunno but it looks pretty reasonable to me, read what all he did, serviced and changed filter at trans, changed diff fluid fr & rear, turned brake rotors, adjusted emerg brake- in fact I don't think you got hosed at all. Pretty average to below average for the work done.

Recent purchase 2002 Yukon SLT with 253000km (157000 miles), has an electrical burp but close to solving it. Engine, tranny, all else work great-especially heated seats at -23 right now. Kinda like the 5.3, love the room for my fat a$$.

I just bought this winter vehicle and now know why it was cheap. When driving along I can loose all electrical power- the engine dies, dash is dead, all lights are gone, all window and door stuff quits. After sitting a while- it comes back on and runs great-till next time. Every once in a while...

Good day all-from Stettler Alberta Canada. You know great white north- oh all of the USA is white now too. Just bought a 2002 Yukon for winter and having wiring problems- will open up post on forum. Good to read about others and their trucks.

Go to Autozone site, they have help area that includes just about every wiring diagram for your unit. You will have to register to access though.
