Hello. My temp gauge never goes past 40 c. Is there an easy fix? All other gauges are fine. Heat is hotter then a ****. Also sometimes my HVAC fan stops working, I slam my glove box and it works. Loose wire? Thanks.

 

loose wire or weak blower motor.

temp gauge as in engine temp or the gauge on the overhead console?

 

Engine temp gauge. My oil pressure gauge use to be stuck all the way to the right but it started to magically work again.

 

i would first verify its the gauge and not the actual reading. hows your truck running anything unusual other then the gauges

 

It runs smooth as a babies bottom, maybe it's the gauge. My gas gauge jumps a little bit each time my signal light blinks as well.
What's the best alternative way to read the temp.? And if it ever does overheat and the gauge is not working will my check engine light still come on?

 

try the thermostat, easy fix sounds like the problem i was having

 

Will try that, I actually have one that I meat to put on my Blazer but never got around to it. So I just follow the upper rad hose to find it?

 

yeah, you have to remove some wire support brackets but overall its an easy easy job.

 

OK, thanks, I'll give it a shot. I'm going to my parents tomorrow where my wounded Blazer is and I'm going to check the fpr and the spider, hopefully it's and easy fix. I went and started it last week and it was running pretty bad, so much gas in the oil. I hope I can revive her.
