I'm Awesome
I did extensive searching before i posted this thread but just wanted to confirm a few things before i started working on my AC
I have a two part question so please stick around to read my second question about Low side pressure readings when you have rear AC.
Some details about my situation
1999 k1500 suburban
The Problem - My blow motor failed a few months ago so i went ahead and replaced the blower motor and the resistor. Recently my blower at high seems weak and if i put it on any speed other than high or low it smells like burning plastic pretty strong.
The process that led to this - On the old parts the resistor was very crispy i noticed also that the black wire that connects to the blower motor was fried. the plastic was burned and discolored and filled with gunk i believe this supplies the power to the blower motor, I cut the plastic connector off and attempted to put a new spade style connector on the wire and then connect it to the blower motor but it was very janky.
Its safe to assume my poor power connector probably fried the resistor or at the least caused the smell?
Does anyone know what style connector the OEM one is? Do i need to use that specific connector or will any style connector work as long as its secure?
Second question related to low side PSI
My suburban is equipped with a rear AC, when i connect a gauge to the low side with just the front AC on my psi reads 45 however when i turn on the rear ac the low psi reads much higher, probably too high. Is there a trick to balancing the two?
my AC works decent with just the front on but with front and rear it gets worse.
