It only blows cold air and won&#039;t switch. Have tried everything including canister and I can&#039;t even get it back to only blowing hot air on defrost! Recently had my car in the air and saw a pump of some type in front of the radiator…assuming this is some sort of air pump? Anyhow there is a white tee that comes off the pump with 2 detachable pieces. Inside is a little spring and washer. One side was completely cracked off. Wondering if this was part of my issue? What piece is this as I&#039;m having trouble finding it on courtesyparts - what does the pump do also (again right beneath the radiator in the front bumper).<br /> <br /> If anyone could guide me to replacement parts or let me know if I can just throw a normal tee in place of it without all the springs inside to block the vacuum that would be great.<br /> <br /> ----<br /> &#039;&#039;&#039;Parker:&#039;&#039;&#039; &lt;small&gt;(2015-07-24 04:05:08)&lt;/small&gt;<br /> <br /> That&#039;s not the headlight washer pump, is it?<br /> <br /> ----<br /> &#039;&#039;&#039;300zxturboftw:&#039;&#039;&#039; &lt;small&gt;(2015-07-24 04:23:12)&lt;/small&gt;<br /> <br /> That makes a lot of sense…considering I took out the washer tank up front…</div>
