. Please let us know if you need anything else to get the problem fixed.

Hello, My tahoe's temperature gauge jumps straight to the highest reading on the gauge and I just started the truck. now my heat is not getting cold either what do you think?

Hello

To better assist you I want to make sure for one we are on the same engine. You said a V8, is it a 5.7L and is the 8th digit of your VIN R?

Next, I want to make sure I understand your question. You said, right when you start the truck the temp gauge goes right to the highest reading?

The second part I don’t understand what you mean. What do you mean you heat is not getting cold either?

As for the first part – do you have plenty of antifreeze in the system?

Please answer the above to better assist you.

The fuel, oil and temp gauge in my truck keep monitoring (stay on) even when the key is removed. The battery, it seems, was drained because of this. Please Help!!

Have you had the ignition switch checked?

I will have the ignition switch checked. Thanks.

Let me know what you find. It may be helpful for others with the same problem.

Thanks,
Joe
