Newbie Forum - Beginner/newbie/general DSM modification questions. First mods, how to run 10's when you haven't run 12's yet, any tech question that doesn't fit in another tech forum.
driving at high speeds?
Edit: Do you mean the blower motor/fan speed or the heat itself getting hot?
Check coolant level also like the guy above said.
Weird, when I did mine I had my drain plug closed and it filled fine. How did you "burp" it?
So are you talking about your temperature gauge... or the actual heater in the cabin of your car?
it works like bleeding your brake lines, if you bleed the lines, tighten them up and then pour brake fluid in the master cylinder you will have air in the lines afterwards...i removed my radiator cap, started her up, run it at about 1500 rpms to let it get to running temperature and when the thermostat opens and coolant starts to cerculate the trapped air gets out, then i just top it off with more coolant
what he's saying is that his heater doesn't work unless he's driving at cruising speeds
if it's not the thermostat, it can either be some blocking in the colling system or air in it
The first time that it happened, I had a small pinhole leak in one of the lines and the coolant leaked out once it was up to temp and the lines were pressurized. I checked the system with a coolant system pressure tester and found the leak. I replaced the line, refilled the coolant, bled the system of air (running with the cap off, filling up the overflow tank) and made sure that the thermostat opened. It happened again this morning, and it was a gusher! I know what I'm doing tonight The reason that the temp fluctuates, as far as I can figure out, is that there is still coolant being pushed through the system as the rpm increases to flow to the heater core, just not enough to flow at idle or low rpms. Happy leak fixing
EDIT: Just re-read the problem. Oops.
Try checking the fuse. You can also test the blower fan by applying 12v to it. If it turns on, then you have a problem somewhere else in the the electronics.
is it under the hood or under the dash b y the pedals?
I dont personally know, but why not just check both areas? Search for any blown fuses and address them.
It is also possible that your blower motor has seized, or just plain stopped working. Try replacing the fuse, but if it is popped, and pops again, check your blower motor and make sure it spins freely.
