Hi,

I just picked up a 2003 Chevy Suburban 1500 LT 4x4

I have several questions:


1) My automatic climate control **** don't work properly (driver VS front passenger, round temp ****). They turn, but the digital display numbers dance around, and won't follow the *** direction. It can take 2 minutes to get the temp all the way up, or all the way down. Is this fixable, or do I need to order new controls?

2) The front differential output shaft seals are bad, and leaking a lot of gear oil. The seal issue is not new, I can tell they have been leaking for a long time. 4x4 works, but there is a clunk in the front end when you engage or disengage the 4x4. Also, there is some error message on the dash. It says something like "service 4x4" or something to that effect. Should I replace the front diff? Should I replace the seals? What triggers the service 4x4 message?

3) My heated seats turn on, but they often turn themselves off almost immediately. Lower temp setting seems to keep the system on longer, but they are not reliable. The driver's side back heats, but I'm not sure that the seat does. Both front seat heaters turns them selves off prematurely.

4) Any suggestions on what remote start system to buy? Looking for range, ease of installation, and ideally - an ignition immobilizer / anti-theft feature.

Thanks guys.

Any input is appreciated.

 

Having the same problem you describe in #1 (temp dancing around when trying to adjust climate control). Did you ever find out an answer to this?

Thanks

 

I am having the same problem with my '03 Suburban right now. (4 wheel drive)
